Price was born in Queens, New York, and began singing in church as a toddler. Her first professional engagement was with George Michael at Madison Square Garden in January 1992. During rehearsals for the Grammy Awards[when?], Price was overheard singing in the rehearsal hall by Mariah Carey while everyone else was on a meal break. Price was later introduced to Carey's husband, Sony Columbia's then CEO Tommy Mottola.[1] She made a name for herself as a backing and guest vocalist, appearing on a number of hit singles such as Mariah Carey's "Fantasy", The Notorious B.I.G.'s "Mo Money Mo Problems", Mase's Feel So Good, and Whitney Houston's "Heartbreak Hotel". She has sung background vocals for Faith Evans, Aretha Franklin, Brian McKnight, SWV and R. Kelly
She released her second album, Mirror Mirror, in 2000 on the Def Soul imprint of Def Jam Records; Island and Def Jam had merged in 1999, with Price and labelmates Dru Hill being reassigned to Def Soul. Mirror Mirror featured the singles "You Should've Told Me" and the Grammy Award nominated[2] "As We Lay", a cover of Shirley Murdock's 1986 hit. A remix of "Love Sets You Free" was issued a single in 2000, produced by Teddy Riley and starring a number of fellow R&B performers. Price was featured in the 2003 film, Bringing Down the House, performing a cover of the 1983 Rufus & Chaka Khan hit "Ain't Nobody".

In 2006, she recorded the song "Why?" for the soundtrack Why Did I Get Married?, the film version of Why Did I Get Married? Priceless Secrets from The Soul of A Woman, in which Price created the role of Sheila alongside Tyler Perry who used the song titles and lyrical content of Price's hit recordings to develop the story. In early 2009, she was featured on Coko's gospel album entitled The Winner in Me on the track "Oh Mary". In June 2010, Price promoted her single "Tired" on The Jazz Joy and Roy syndicated radio show as "some of the best work of my career to date."[4] The song was also featured in Tyler Perrys 2011 film Madea's Big Happy Family. On February 9, 2012, in a pre-Grammy party to celebrate Price's nominations, the singer sang "Jesus Loves Me" with Whitney Houston in what turned out to be Houston's last public performance two days before her death. In September 2009, it was announced she would be joining Deborah Cox and Tamia to form the super group The Queen Project. The women seek to empower women of all ages, races and backgrounds by doing a number of community service projects.[5]
