Born on September 24, 1985, Miles is the daughter of a single mother Emma Miles from Naples, Florida. Her father died when she was four years old after he was paralysed from the neck down following a car accident. Miles began singing at church. She fell in love with music when she saw “Captain E.O” at Epcot with her mother and brother in Orlando at the age of four. Miles grew up in Naples, Florida, and joined her first cheerleading team at the age of five, and her first part in a school musical was at the age of seven. Miles continued competitive cheerleading until the age of 18. Also a trained gymnast, Miles played soccer and volleyball at her school and loved performing arts.

Miles performed the song “Honky Tonk Women” for The Rolling Stones week – her performance was good despite being ill with laryngitis. The next day, Miles was sent to the bottom three, along with her friend and roommate Lacey Brown and Tim Urban. Simon Cowell commented “one of them was worth saving” but did not reveal who it was. She and Urban were later proclaimed as “safe” leaving her friend Brown behind. Brown was not saved by the judges and was eliminated. Miles performed “Against All Odds (Take a Look at Me Now)” by Phil Collins for Billboard No. 1 Hits week. Her performance was panned by the judges largely due to Miles still suffering from laryngitis. She was eliminated from the show on March 24, 2010.

Miles was a panel member, and also performed some of her original material, at the 1st Annual Reality Rocks Expo in April 2011. She also stars in the musical Beehive.

In April 2011 Miles was driving when her car caught fire. She had to escape through the window as the doors were locked after the electric system shut down.

On June 26, 2011, Miles released her first original single on iTunes titled, “Definition of Me”.
