Evans was born on June 10, 1973, in Lakeland, Florida, to an African American mother, Helene Evans, a professional singer. Her father, Richard Swain was a musician who left before Evans was born (Evans has said “I’ve heard people mumble something about him being Italian, but I don’t know for sure”). A half-year later, 19-year-old Helene returned to Newark, New Jersey and left Faith with her cousin Johnnie Mae and husband Orvelt Kennedy, the foster parents of more than 100 children they raised during the time that Faith lived with them. Faith had known Johnnie Mae and Orvelt Kennedy as her grandparents. It was not until a couple of years later that Helene’s career floundered and she tried to take Evans back home. Faith, however, was afraid to leave what she had “been used to,” and instead, Helene relocated next door.

Raised in a Christian home, Evans began singing at church at age two. At age four, she caught the attention of the congregation of the Emmanuel Baptist Church in Newark when she sang The 5th Dimension’s song “Let the Sunshine In”. While attending University High School in Newark, she sang with several jazz bands and, encouraged by Helene, entered outside pageants, festivals and contests, where her voice would be noticed and praised. After graduating from high school in 1991, Evans attended Fordham University in New York City to study marketing but left a year later to have daughter Chyna with music producer Kiyamma Griffin. In 1993, she relocated to Los Angeles, where she worked as a backup vocalist for singer Al B. Sure!, when she was noticed by musician Sean “Puff Daddy” Combs. Impressed with her, Combs contracted her as the first female artist to his Bad Boy Entertainment record label during 1994.

A year before, on August 4, 1994, Evans married rapper and label mate Christopher “The Notorious B.I.G.” Wallace, after having met him at a Bad Boy photoshoot. The couple had one child together, Christopher George Latore Wallace Jr..

Newly contracted to Bad Boy Records, Evans was consulted by executive producer Combs to contribute backing vocals and writing skills to Mary J. Blige’s My Life (1994) and Usher’s self-titled debut album (1994) prior to starting work on her debut studio album Faith. Released on August 29, 1995, in North America, the album was a main collaboration with Bad Boy’s main producers, The Hitmen, including Chucky Thompson and Combs, but it also resulted in recordings with Poke & Tone and Herb Middleton. Faith became a success based on the singles “You Used to Love Me” and “Soon as I Get Home”. The album was eventually certified platinum with 1.5 million copies sold, according to RIAA.

Evans became involved in the East Coast–West Coast hip hop rivalry which dominated the rap music news at the time after allegations of an affair with Tupac Shakur. Wallace was murdered in a yet-to-be-solved drive-by shooting in Los Angeles, California in March 1997. During early 1997, after her separation from Wallace, but before his death, Evans’ friend Missy Elliott introduced her to record company executive Todd Russaw. Faith began dating Russaw during her and Wallace’s separation and after Wallace died, Evans became pregnant by Russaw. The couple had their first son Joshua on June 10, 1998 (on her 25th birthday). During the summer of 1998, Evans and Russaw were married, and on March 22, 2007, they had their second son Ryder Evan Russaw.

After Biggie’s murder on March 9, 1997, Combs helped Evans produce her tribute song named “I’ll Be Missing You”, based on the melody of The Police’s 1983 single “Every Breath You Take”. The song, which featured Combs, Evans, and the all-male group 112, became a worldwide number-one success and debuted at number one on the US Billboard Hot 100 chart during 1997, scoring that for eleven weeks. It eventually won Puffy and Evans the 1998 Grammy Award for Best Rap Performance by a Duo or Group. The next year, she received another two Grammy nominations for “Heartbreak Hotel”, a collaboration with singers Whitney Houston and Kelly Price, that scored number two on the Billboard Hot 100 chart.

Two years in the making, Evans’ second studio album, Keep the Faith, was released in October 1998. Almost entirely written and produced by her, Evans considered the album difficult to complete as she had initially felt discouraged about the progress at first. Upon its release, however, the album earned generally positive reviews by music critics, with Allmusic noting it “without a doubt a highlight of 1990s soul-pop music”. Also enjoying commercial success, it eventually went platinum and produced the top ten singles “Love Like This” and “All Night Long” (released March 30, 1999) prompting Evans to start an 18-city theater tour with Dru Hill and Total the following year.

During 2003, Evans acted in the MTV-produced romantic comedy The Fighting Temptations in which she appeared in a brief but major role portraying a single mother and night club singer. Filmed in Columbus, Georgia and headed by Cuba Gooding Jr. (her character is his mother) and Beyoncé Knowles, the film garnered mixed reviews by critics, but scored top three of the U.S. box office, resulting in a domestic gross of US$30.2 million. In addition, Evans recorded a contemporary cover version of Donna Summer’s 1978 success “Heaven Knows” for the film which her characters performs during one of the first in sequence in the film. The accompanying soundtrack scored the top twenty of the U.S. Billboard 200.

Evans’ third album on the Bad Boy label, named Faithfully (2001), involved her working with a wider range of producers, including The Neptunes, Mario Winans, Buckwild, Vada Nobles, Cory Rooney, and others. Her first project with husband Todd Russaw as executive producer and creative partner, the album scored number 14 on the Billboard 200 album chart and number two on the Top R&B/Hip-Hop Albums chart, eventually being certified platinum, but yielded moderately successful singles, with the Jennifer Lopez-written “I Love You” becoming the only top twenty entry. Released amid Bad Boy Records’ transition from distributor Arista Records to Universal, Evans felt Faithfully received minimum assistance by the company, and during 2004, she finally decided to end her business with Bad Boy as she was convinced Combs couldn’t improve her career any more due to his other commitments. In January 2004, Evans and Russaw were arrested and charged with possession of marijuana and cocaine and an improper tag violation during a traffic stop in Hapeville, a suburb of Atlanta, Georgia.

During 2004, Evans earned a brief guest stint on the UPN situation comedy Half & Half. Evans announced that she had been working on a synopsis for her own situation comedy that would be based largely on her life but with a more comedic aspect. It is unknown whether she has officially pitched the sitcom to any television networks at this time.

After ending with Bad Boy Entertainment Evans contracted with Capitol Records company, becoming the first contemporary R&B artist to do so, and started work on her fourth studio album The First Lady, named after her nickname on her former label. As opposed to having an in-house team of producers who supplied most of the previous material, she and Russaw were able to gain more creative control of the album and consulted producers such as Bryan-Michael Cox, Jermaine Dupri, Mike Caren, Pharrell Williams, and Chucky Thompson to contribute to it. Upon its release in April 2005, The First Lady scored at number two on the Billboard 200 and number one on the Top R&B/Hip-Hop Albums chart, becoming Evans’ best-charting album to date. It was eventually certified gold by the RIAA. At the end of the year, Evans released A Faithful Christmas, a holiday album of traditional Christmas songs and original tracks. The effort would become her last release on Capitol Records as the company was bought during 2007.

Evans released her autobiographic book called Keep the Faith: A Memoir on August 29, 2008. Written with Aliya S. King, it detailed the singer’s life, but also discussed Evans’ controversial relationship with her late husband, the Notorious B.I.G.:

Following a 5-year hiatus Faith Evans created her own record label imprint in 2010. She named the imprint Prolific Music Group and hired top talent to build the record label from scratch. Evans began recording songs with Keyshia Cole, Redman, Snoop Dogg and Raekwon, among others for the labels freshman album. Evans signed a deal with independent record label E1 Entertainment later that year. Her fifth studio album Something About Faith was released on October 5, 2010, in the United States, where it debuted and peaked at number fifteen on the Billboard 200 and number one on the Independent Albums chart. Something About Faith has spawned the leading single “Gone Already”, which spent over thirty-three weeks on the US Billboard Hot R&B/Hip-Hop Songs chart, where it peaked at number twenty-two.

In August 2010, Evans was arrested on suspicion of misdemeanor drunken driving, after being stopped at a checkpoint in Marina del Rey, California. In 2011, Evans filed for divorce against Russaw. The couple agreed to spend 13 weeks in a drug-treatment program in exchange for halting any further prosecution of their drug-possession case. In May 2011, Evans and Russaw announced they were getting a divorce, and stated they would like to keep it quiet for the children’s sakes.

In November 2010, several sources stated that Faith would portray Motown star Florence Ballard of the Supremes in an upcoming biopic, Blondie: The Florence Ballard Story. With the blessing of Ballard’s three daughters, Faith later appeared on the Wendy Williams Show to promote this role. In July 2014, Rolling Stone reported that the movie, thought to be titled “Blondie”, was in fact a con artist’s scam.

In 2012, Evans co-executive produced and became a cast member on the TV One reality show R&B Divas: Atlanta alongside fellow R&B singers Nicci Gilbert, Syleena Johnson, Keke Wyatt and Monifah. The show offered an inside look at how the singers balance their music careers and personal lives as they work towards producing an Evans-led compilation album, R&B Divas (2012), in memory of Whitney Houston. Broadcast to rating records for the network, the series produced a spin-off titled R&B Divas: Los Angeles and was renewed for two further seasons. Evans, who left the show following its second season, earned a Grammy nomination for Best R&B Album at the 55th awards ceremony.

In August 2013, Evans confirmed she had begun work on her sixth studio album Incomparable, involving contribution from Chucky Thompson, Mike City, KeKe Wyatt, B.Slade and Karen Clark Sheard of The Clark Sisters. “I Deserve It”, a record featuring recurring collaborator Missy Elliott and her protégée Sharaya J, was released on August 25, 2014, as the album’s lead single and peaked at number 19 on Billbord’s Adult R&B Songs chart. Released by Prolific Music Group and BMG Rights Management on November 24, 2014, Incomparable debuted at number 27 on the US Top R&B/Hip-Hop Albums and number 17 on the US Independent Albums chart.

In 2014, Faith showed support for Little Kids Rock by donating items for auction to raise money in support of music education in public schools.

In 2016, Evans announced that she was finishing a posthumous Notorious B.I.G. album titled The King & I, which will feature duets with her late husband. The album was released on May 19, 2017.

As of 2018, she is married to producer and Love & Hip Hop: Atlanta star Stevie J. The couple released the hit song “A Minute”. Between 2015 and 2019 Evans-Jordan appeared in several episodes of Love & Hip Hop Atlanta, and Leave It to Stevie along side then friend Stevie J.

In May 2020, Evans was arrested for felony domestic violence against producer Stevie J. She was released on bond.
