She’s just a girl, the “Hollaback Girl,” with a backside that’ll make you holler. She’s blonde, with pouting lips and an attitude that screams rock star. That’s because she’s Gwen Stefani, lead lungs from No Doubt and Anaheim, California’s favorite daughter--sorry Minnie Mouse. Besides owning the Billboard charts, Gwen is an aspiring actress, with her debut in the not-too-shabby Martin Scorsese-helmed The Aviator (2004), where she played another blonde bombshell, Jean Harlow. Gwen is married to another lead singer, Gavin Rossdale from Bush. Want to see Gwen’s bush? Not yet, at least, though some of her videos show her off in a skinless if not un-sexy fashion. Speaking of fashion, she has a clothing line called L.A.M.B., and if she models her creations Mr. Skin will slaughter his lamb.
