Cameron Diaz was looking very chic leaving the Sunset Marquis Hotel this weekend. She certainly didn't look as energetic as her new wax figure but maybe it was a real late rendezvous that night. We haven't seen much of the star since she was in NYC shooting What Happens in Vegas and supposedly dating John Mayer, but luckily we'll get to see her shine at the Oscars this Sunday. Cam will be presenting an award after strutting her stuff on the red carpet. You guys were almost split about last year's look, so this is her chance to redeem herself. By the way — have you filled out your Oscar ballot yet? It's super easy and you can win prizes!

You're asking why is Cameron going--you should be asking why the hell Miley Cyrus is going. haha. 
She always looks fabulous.
