Gwen Stefani

Have you seen Gwen Stefani onstage, on the red carpet, or on camera in one of her countless MTV appearances? She's a living testimony to the joys of caffeine. She's a human energy drink. And, in case you haven't noticed, she's critic-proof, too, whether we're talking those outrageous styles she picks out of what has to be a studio lot costume room (have you seen her sexy pirate costume?), her hairstyles (which change color as frequently as the seasons), or her senseless lyrics ("Oooh, oooh, this my shit, this my shit" and, of course, "B-A-N-A-N-A-S"). She also goes by Gwendolyn or Gwen, and everyone knows both names are, like, so not cool -- they're grandma names. Yet, like everything else Gwen Stefani touches, her name has become rock gold . . . or is it platinum? Just like her first solo outing, Love. Angel. Music. Baby., not to mention this month's hair-color selection.
