Ashlee Simpson is the husky-voiced singer of the pop single "Pieces of Me," but she's nearly as famous for being the younger sister of singer Jessica Simpson
. Ashlee Simpson studied dance as a child and got her start in show business backing up her sister on stage. By 2002 Ashlee was a semi-celebrity in her own right, appearing as a regular cast member on the television series 7th Heaven
and making her film debut in the 2002 comedy The Hot Chick
. In 2004 she appeared on the MTV reality show The Ashlee Simpson Show
as a prelude to releasing her first pop album, Autobiography
. She's since made appearances on screen and stage and has released more records, including I Am Me
(2005) and Bittersweet World
(2008), both of which sold modestly and got little love from the critics. Ashlee Simpson married bassist Pete Wentz on 17 May 2008; he was formerly with the band Fall Out Boy. Simpson filed for divorce in January of 2011.
