Ashlee Simpson (born October 3, 1984) is an American pop rock singer-songwriter and an occasional actress. She is the younger sister of pop singer Jessica Simpson.
Simpson rose to prominence in mid-2004 through the success of her number-one debut album Autobiography and the accompanying reality series The Ashlee Simpson Show. Simpson received widespread derision when she used a pre-recorded vocal track for a performance on Saturday Night Live in October 2004. Following a North American concert tour and an unsuccessful film appearance, Simpson released a second number-one album, I Am Me, in late-2005.
