Well, she's getting a bit long in the tooth to pull off the lolita deal, so her handlers have to transition her into something new for the 20s/30s crowd. Making her the next Madonna would be the end goal, but having seen the latest incarnation during the Superbowl, and seeing the trailers for her new movie (b-fest here it comes!), I don't think it's going to happen.
Her average talent and looks (by hollywood/music industry standards, of course) would be acceptable if she had star power personality. She just isn't that exciting once you go beyond the schoolgirl/lust fantasy.
Gwen Stefani on the other hand

Though you can tell the "edge" is being produced out of No Doubt's sound in favor of a more pop direction, which is too bad IMHO.
