Ashlee Simpson

Ashlee Simpson, younger sister of singer Jessica Simpson, is one of the most fascinating pop-culture phenomena of the early 2000s. Following a stint on the squeaky-clean television drama "7th Heaven," the prefabricated sensation's singing career was launched in 2004 with the release of AUTOBIOGRAPHY. Despite an infamous lip-synching debacle on SNL, fans continued to gobble up Ashlee's pop take on alternative rock. Simpson is an intriguing study in insta-fame and, as her 2005 release I AM ME proved, a dependable source for catchy chart toppers.
