With a regular role as Cecilia in WB’s hit TV Seventh Heaven , the upcoming Ashlee reality series on MTV and debut album bowing in July, Ashlee is about to emerge from the shadows.

“I’ve always been obsessed with music,” says Ashlee, who adds that her tastes—along with her album—are not at all like older sister Jessica’s. “We’re into totally different bands and artists.”

Produced by John Shanks (Michele Branch, Sheryl Crow, Melissa Etheridge, Alanis Morrissette, Unwritten Law), the new album has elements of rock, punk, and pop, recalling Ashlee’s own favorite bands—ranging from Janis Joplin and Steve Nicks to Pat Benatar, the Pretenders and Blondie through Fiona Apple, Hole and Green Day.

Ashlee co-wrote every song on the album. “I just wanted to go in and make a record and not worry about what genre it would be,” she says. “I went in to have a good time and did. It’s a rock record, with a cool edge to it. It’s the first time people are getting to hear what I sound like.”

The first single, “Pieces of Me,” is a full-throttle rocker about a best friend who brings comfort at the end of a long, stressful day of work. “It’s like a sigh,” she says. “When I finally see him, all the other dramas fade away.”

“Autobiography” plays around with her public image, daring those who want to know her to walk up and “baby just ask me.” The tongue-in-cheek rave-up “LaLa” is about sexual fantasies, with Ashlee role-playing as an alley cat and a French maid, but all in fun. “There’s a lot of sarcasm in that song,” she says. “It’s something every girl thinks about, so I decided to make a joke about it. It’s one of the songs you can dance around to.”

The Waco, TX-born Ashlee has been dancing since she was three, and by 11, she was the youngest person ever admitted into the prestigious School of American Ballet. She moved to L.A. with her parents and Jessica when she was 14, pursuing an acting career and dancing in her sister’s stage show, but dreaming of doing music all the while.

She went on to make appearances on Malcolm in the Middle and The View before landing a regular role in Seventh Heaven. Last year, she had the track “Just Let Me Cry” on Disney’s Freaky Friday soundtrack, and then began recording earlier this year on breaks from filming the TV show.
