Demetria Devonne Lovato was born on August 20, 1992 in Albuquerque, New Mexico to former Dallas Cowboys cheerleader Dianna De La Garza (née Lee Smith) and engineer and musician Patrick Martin Lovato. She has an older sister named Dallas; a younger maternal half-sister, actress Madison De La Garza; and an older paternal half-sister named Amber, whom she first spoke with when she was 20 years old.

Lovato was raised in Dallas, Texas. She began playing piano at age seven and guitar at ten, when she began dancing and acting classes. In 2002, Lovato began her acting career on the children’s television series Barney & Friends, portraying the role of Angela. Lovato appeared on Prison Break in 2006 and on Just Jordan the following year. Lovato later recalled in an interview on The Ellen DeGeneres Show that due to her acting career, she was bullied and requested homeschooling, through which she eventually received her high-school diploma.

From 2007 to 2008, Lovato played Charlotte Adams on the Disney Channel short series As the Bell Rings. Lovato auditioned for the channel’s television film Camp Rock and series Sonny with a Chance during 2007 and got both roles. Lovato played the lead character, aspiring singer Mitchie Torres, in Camp Rock. The film premiered on June 20, 2008, to 8.9 million viewers. Gillian Flynn of Entertainment Weekly wrote that Lovato’s acting skills were underwhelming and that she “has the knee-jerk smile of someone who is often told she has a great smile”. The film’s soundtrack was released three days earlier; however, the music was considered less current than that of High School Musical. It debuted at number three on the US Billboard 200, with 188,000 units sold in its first week of release. Lovato sang four songs on the soundtrack, including “We Rock” and “This Is Me”. The latter, Lovato’s debut single, debuted at number 11 on the US Billboard Hot 100 and later peaked at number nine, marking her first entry on the chart. That summer, Lovato signed with Hollywood Records and began her Demi Live! Warm Up Tour before the release of her debut studio album, and appeared on the Jonas Brothers’ Burnin’ Up Tour.

Lovato’s debut studio album, Don’t Forget, was released on September 23, 2008, and was met with generally positive reviews from critics. Michael Slezak of Entertainment Weekly said, “Demi Lovato might satisfy her ‘tween fans but she won’t be winning any rockers over with Don’t Forget”. The album debuted at number two in the US, with first-week sales of 89,000 copies. Ten of its songs were co-written with the Jonas Brothers.

“Skyscraper”, the lead single from Unbroken, was released on July 12, and was noted for its messages of self-worth and confidence. It debuted at number ten in the US, selling 176,000 downloads during the first week of release, becoming Lovato’s highest first week sales at the time. The song also became Lovato’s highest-charting single since “This Is Me” peaking at number nine in July 2008, and it also debuted at number two on the Hot Digital Songs chart. “Skyscraper” received the Best Video With a Message award at the September 2012 MTV Video Music Awards, and the track was also certified Platinum by the RIAA and Silver by the BPI. The album’s second and final single, “Give Your Heart a Break”, was released on January 23, 2012, and later peaked on the Billboard Hot 100 at number 16, making Lovato’s fourth highest-charting song to that point. It peaked at number 12 on the US Adult Top 40 chart and number one on the US Pop Songs chart. It also became the longest climb by a female artist to reach No. 1 in the Pop Songs chart history, until 2019, when Halsey’s feature on “Eastside” broke the record. The song was certified triple Platinum in the US; As of October 2014, “Give Your Heart a Break” has sold 2.1 million digital copies. Billboard has ranked the song as Lovato’s best, calling it “timeless”.

Lovato’s second studio album, Here We Go Again, was released on July 21, 2009; she described its acoustic style as similar to that of John Mayer. The album received favorable reviews from critics who appreciated its enjoyable pop-rock elements, echoing reviews of Don’t Forget. Lovato’s first number-one album, it debuted atop the Billboard 200 with first-week sales of 108,000 copies, and was later certified Gold. The album’s lead single and title track, “Here We Go Again”, debuted at number 59 on the Billboard Hot 100, and managed to peak at number 15, becoming Lovato’s highest-charting solo single to that point. The song also peaked at number 68 on the Canadian Hot 100 and number 38 in New Zealand. “Here We Go Again” was additionally certified Platinum in the US. The album’s second and final single, “Remember December” failed to match the success of its predecessor, but peaked at number 80 on the UK Singles Chart. Lovato made her first 40-city national concert tour, Live in Concert, in support of Here We Go Again. The tour, from June 21 to August 21, 2009, had David Archuleta, KSM and Jordan Pruitt as opening acts. Lovato and Archuleta received the Choice Music Tour award at the 2009 Teen Choice Awards. Lovato was featured alongside the Jonas Brothers, Miley Cyrus and Selena Gomez on the song “Send It On”, a charity single and the theme song for Disney’s Friends for Change. All proceeds from the song were donated to environmental charities supported by the Disney Worldwide Conservation Fund. Lovato recorded “Gift of a Friend” as a soundtrack for the Disney movie Tinker Bell and the Lost Treasure. The movie was released in October 2009.

Lovato has also raised awareness for health and mental health issues; for her efforts to fight mental health stigma, she was honored with the Artistic Award of Courage by The Jane and Terry Semel Institute. In May 2009, Lovato was named an Honorary Ambassador of Education by the American Partnership For Eosinophilic Disorders. In December 2011, Lovato criticized Disney Channel for airing episodes of Shake It Up and So Random!, in which characters joked about eating disorders. Disney Channel later apologized and removed the episodes from the network’s broadcast and video on demand services. In May 2013, she was cited for her dedication to mentoring teens and young adults with mental-health problems at a National Children’s Mental Health Awareness Day hosted by the Substance Abuse and Mental Health Services Administration in Washington. Lovato has paid treatment costs for mentally-ill patients through the Lovato Treatment Scholarship Program, named for her late father, since 2013. Her speech at the 2016 Democratic National Convention focused on raising awareness for mental health. In September 2017, Lovato was named a Global Citizen ambassador for championing the mental health of thousands of children displaced within Iraq and other communities” and helped “fund the expansion of a Save the Children pilot program, Healing and Education through the Arts, to violence-scarred young people living around Kirkuk and Saladin Governorate, Iraq”.

In 2010, Lovato and Joe Jonas recorded “Make a Wave” as the second charity single for Disney’s Friends for Change. In May of that year, Lovato guest-starred as Hayley May, a teenager with schizophrenia, in the sixth-season Grey’s Anatomy episode, “Shiny Happy People”. Although critics praised her versatility, they were underwhelmed by her acting and felt that her appearance was designed primarily to attract viewers. Later that year, she headlined her first international tour, Demi Lovato: Live in Concert, and joined the Jonas Brothers: Live in Concert tour as a guest.

Camp Rock 2: The Final Jam, with Lovato reprising her role as Mitchie Torres, premiered on September 3, 2010. Critics were ambivalent about the film’s plot, and it has a 40-percent approval rating on Rotten Tomatoes. However, Lovato’s performance was called “dependably appealing” by Jennifer Armstrong of Entertainment Weekly. The film premiered to eight million viewers, the number-one cable television movie of the year by the number of viewers. Its accompanying soundtrack was released on August 10 with Lovato singing nine songs, including “Can’t Back Down” and “Wouldn’t Change a Thing”. The soundtrack debuted at number three on the Billboard 200, with first-week sales of 41,000 copies. Jonas Brothers: Live in Concert was reworked to incorporate Lovato and the rest of the film’s cast; it began on August 7, two weeks later than planned. The Sonny with a Chance soundtrack was released on October 5; Lovato sang on four tracks, including “Me, Myself and Time”. It debuted (and peaked) at number 163 on the Billboard 200, her lowest-selling soundtrack. In November 2010, Lovato announced her departure from Sonny with a Chance, putting her acting career on hiatus and ending the series; she later said that she would return to acting when she felt confident doing so. Her departure led to the actual spin-off series So Random! with the Sonny cast, featuring sketches from the former show-within-a-show. The series was canceled after one season.

Lovato had suffered from bipolar disorder, Anorexia nervosa (binge type), self-harm, and being bullied before she went into rehab at age 18. On November 1, 2010, Lovato withdrew from the Jonas Brothers: Live in Concert tour, entering a treatment facility for “physical and emotional issues”. It was reported that she decided to enter treatment after punching female dancer Alex Welch; her management and family convinced her she needed help. Lovato said she took “100 percent, full responsibility” for the incident. On January 28, 2011, Lovato completed inpatient treatment at Timberline Knolls and returned home. She acknowledged that she had bulimia, had cut herself, and had been “self-medicating” with drugs and alcohol “like a lot of teens do to numb their pain”. She added that she “basically had a nervous breakdown” and was diagnosed with bipolar disorder during her treatment. Lovato later said that she had used cocaine several times a day and smuggled cocaine onto airplanes.

Lovato is a vocal anti-bullying advocate. In October 2010, she served as spokeswoman for the anti-bullying organization PACER and appeared on America’s Next Top Model to speak out against bullying.

Lovato released her third studio album, Unbroken, on September 20, 2011. Begun in July 2010, the album experimented with R&B and featured less pop rock than her first two albums. Lyrically, Unbroken encompassed more mature themes as opposed to Lovato’s previous works, with some songs focusing on her personal struggles. The album and its stylistic change received mixed reviews from critics, who praised Lovato’s vocals and saw a growth in her musicianship due to the songs focusing on her struggles, but criticized the album’s “party songs” and found the music to be more generic than her previous efforts. Unbroken debuted at number four in the US, selling 97,000 copies in its first week of release; it was later certified Gold.

On her 18th birthday, Lovato purchased a Mediterranean-style house in Los Angeles for her family; however, she decided to live in a “sober house” in Los Angeles after leaving rehab in January 2011.

Lovato celebrated the six-year anniversary of her sobriety on March 15, 2018.

Lovato’s fourth studio album, Demi, was released on May 14, 2013. The album features influences of synthpop and bubblegum pop and was met with generally positive reviews from music critics. Although Jon Carmichael of The New York Times found Lovato’s transition fun, according to Entertainment Weekly it signified a less-mature image. The album debuted at number three in the US, with first-week sales of 110,000 copies, the best-selling debut week of Lovato’s discography. It was also successful internationally, charting in the top ten in New Zealand, Spain and the UK. The album has been certified Gold in the US.

Lovato had no interest in forging a relationship with her birth father, Patrick, after his divorce from her mother. She has been vocal about her abusive and strained relationship with him and once stated, “He was mean, but he wanted to be a good person. And he wanted to have his family, and when my mom married my stepdad, he still had this huge heart where he said, ‘I’m so glad that [he’s] taking care of you and doing the job that I wish I could do’.” Patrick died of cancer on June 22, 2013. After his death, Lovato said that he had been mentally ill, and in his honor she created the Lovato Treatment Scholarship Program.

During the album’s production, Lovato commented: “I’ve already started recording for my new album, and I have plans to record during the tour. The sound just evolves into everything that I’ve been and everything that I want to become.” She further stated, “I’ve never been so sure of myself as an artist when it comes down to confidence, but not only personal things, but exactly what I want my sound to be and what I know I’m capable of and this album will give me the opportunity to show people what I can really do.”

Lovato released the lead single from Confident titled “Cool for the Summer” on July 1, 2015.

She stated: “I wasn’t working my program. I wasn’t ready to get sober. I was sneaking it on planes, sneaking it in bathrooms, sneaking it throughout the night. Nobody knew.”

Lovato identifies as a feminist. In a 2017 interview with Dolly magazine, she explained that “Feminism … doesn’t have to mean burning bras and hating men” but instead “standing up for gender equality and trying to empower our youth. And showing women that you can embrace your sexuality and you deserve to have confidence and you don’t need to conform to society’s views on what women should be or how you should dress. So, I think it is just about supporting other women and empowering other women.” In May 2017, Lovato partnered with Fabletics to create a limited edition activewear collection for the United Nations Foundation’s Girl Up campaign to fund programs for “the world’s most marginalized adolescent girls”.

On June 21, 2018, Lovato released the single “Sober” in which she revealed she had relapsed following six years of sobriety.

In December 2018, Lovato took to Twitter to dismiss rumors regarding her overdose and went on to thank her fans, writing: “If I feel like the world needs to know something, I will tell them MYSELF. All my fans need to know is I’m working hard on myself, I’m happy and clean and I’m SO grateful for their support.” She went on to add that some day she would “tell the world what exactly happened, why it happened and what my life is like today.. but until I’m ready to share that with people please stop prying and making up shit that you know nothing about. I still need space and time to heal.”

In January 2019, the album was certified platinum by the RIAA, and has sold one million copies in the United States. In May 2015, Billboard revealed that Lovato was in the process of starting an “artist-centric” new record label, Safehouse Records, of which she would be co-founder and co-owner. The label would be a partnership between Lovato, Nick Jonas, and her then-manager Phil McIntyre, and will form part of a new collaborative arrangement with record label Island. Confident was released through the new venture deal. This would be Lovato’s second multi-label venture of her career; she was formerly part of Jonas Records, a UMG/Hollywood/Jonas Brothers partnership, which is now defunct.

On May 11, 2019, via an Instagram post, Lovato revealed that she had signed with a new manager, Scooter Braun. She shared that she “couldn’t be happier, inspired and excited to begin this next chapter”.

In October 2019, Lovato received backlash for accepting a free trip to Israel from private donors and its Ministry of Jerusalem Affairs due to the Israeli–Palestinian conflict; she later regretted the journey but insisted that it was meant to be a spiritual experience, not a political statement.

In January 2020, it was revealed that Lovato would make her return to music later that month with a performance of her comeback single “Anyone” at the 62nd Annual Grammy Awards. The song was released on iTunes immediately following the performance. It marked Lovato’s first musical appearance since her hiatus.

Lovato was lauded for her performance of “The Star-Spangled Banner” at Super Bowl LIV in 2020. Patrick Ryan of USA Today commended her for delivering a “flawless performance” and “reminding us she’s one of the best vocalists in the industry today.” He went on to note that “she hit all the high notes with ease” and ultimately “even added some of her own riffs” which he says resulted in “a rendition that was uniquely and phenomenally hers.”

Lovato describes her sexuality as fluid, and has said she is open to finding love with someone of any gender. In July 2020, she labeled herself queer in a social media statement mourning the death of Glee co-star Naya Rivera.

On July 23, 2020, Lovato announced her engagement to actor Max Ehrich. They had begun dating four months earlier. The couple called off their engagement that September.

Lovato later revealed in a 2020 interview on The Ellen DeGeneres Show that her worsened struggles with bulimia in 2018 contributed to her eventual drug overdose, as she relapsed three months prior to the incident due to being extremely unhappy. She attributed these struggles to the extreme measures that her then-manager, Phil McIntyre, took to control what she ate. Lovato further explained that, along with the controlling nature of her management team, they did not provide her with the help she needed, commenting: “People checking what my orders at Starbucks were on my bank statements… just little things like that… it led me to being really unhappy and my bulimia got really bad and I asked for help and I didn’t receive the help that I needed.” Moreover, she recalled that her thought process the night she relapsed following six years of sobriety was as follows: “I’m six years sober and I’m miserable. I’m even more miserable than I was when I was drinking. Why am I sober?” When Lovato confronted her management team about her thoughts, they responded with, “You’re being very selfish, this would ruin things for not just you but for us as well,” which she says made her feel “completely abandoned” due to triggering her underlying abandonment issues with her birth father, and so she “drank that night”.
