PHOTOS: The Many Sides of Ashlee Simpson

Ashlee Simpson-Wentz shows off the many side of her personality, from sweet to rocker to sophisticated, in a chiffon, leather and tweed ensemble at the CBS, CW and Showtime TCA party on Monday in Pasadena.

Jessica's kid sister returns to TV (you might remember she had a recurring role on 7th Heaven), in The CW's reboot of '90s hit Melrose Place. She was joined at the upfront by fellow MP resident (and daughter of Partridge Family alum and '70s pop star David Cassidy) Katie Cassidy.
