Ashlee Simpson.

AGE 19 HOMETOWN Dallas, Texas, but she now lives in Los Angeles. WHY YOU KNOW HER Even though on her debut CD Autobiography she sings, "I was living in the shadow of someone else's dream," Ashlee refuses to live in the shadow of her sister Jessica Simpson (Newlyweds) and is making her own mark instead. You know her as Cecilia on WB's 7th Heaven, and now she has her own MTV reality series The Ashlee Simpson Show. GIRLS ON FILM "Jessica couldn't believe I was doing a show also. Now, when I come over, I bring over my cameras, while there's always a crew around her house. It's actually quite funny. Jess taught me it's cool to be yourself." GIRLS WHO SING "I've been singing since I was young, but I didn't always know I could really sing. I kind of thought that was Jessica's thing and that I was supposed to do something else. Then, I started writing my own music and decided I really liked my songs. Just because I have a sister who sings doesn't mean I can't be a singer too." LITTLE DREAMER "The first CD I remember listening to was something my cousin played for me when I was about 4, which was Van Halen. So I used to listen to their CDs and wear their T-shirts. My cousin was the one who wanted me to be a rocker!" TINY DANCER Did we mention that, at 11, Ashlee was the youngest person ever admitted into the prestigious School of American Ballet in New York? At 14, she was a backup dancer for her sister's stage tour. STILL DANCING AFTER ALL THESE YEARS "If it's a Friday and I've been working all week, I like to go out and go dancing with my girl friends. I like to do boring, stupid stuff in my spare time when I'm not working. I like to sit around or go bowling."
