Who's That Girl?

UPDATE: A friend tells me he thinks this is actually Audrina's sister, who apparently appears on "The Hills" now (only I didn't know that because I no longer watch it). All the wire service captions say it's Audrina, but they're notoriously bad about getting their subjects' names correct.

While I'm proud to report that I gave up "The Hills" this season cold turkey, I couldn't help but notice something was very different about cast member Audrina Patridge in these wire photos I saw of her, with that dude from "Beverly Hills, 90210," at the "Waiting in Beijing" premiere in L.A. this week. The once-adorable California girl is now almost unrecognizable, although I can't quite put my finger on what she's done to herself -- other than lay off the spray tan. My guess is some kind of oral surgery to compensate for her weak upper lip. But now that it's been "fixed," she's like Jennifer Grey without a quirky nose -- cute, but characterless. Bad move, Audrina. Worse than dating Justin Bobby (oops, there I go again ...).
