Ashlee Simpson July 11, 2008

Ashlee Simpson sets out to support her latest album, 'Bittersweet World.' Simpson started as an actress appearing on 'Malcolm in the Middle' and '7th Heaven.' From there, Geffen Records released her debut album in 2004 as MTV debuted her own reality show. A slight "vocal mishap" on 'Saturday Night Live' in December 2004 may have been a bump in the road, but Simpson managed to get past that. 'Bittersweet World' is Simpson's third release, following 2004's 'Autobiography' and 2005's 'I Am Me,' both of which topped The Billboard 200 and led to sold-out tours.
