Charlize Theron showed up at the Oscars to cheer on Jeremy Renner her new squeeze from "The Hurt Locker."
She looked a hundred times different to the Theron who did the rehearsal the night before.
On Saturday night, Theron, wearing just heels and jeans and no make-up, practiced her lines and angles for the camera.
Chatting with a producer, she said, "Well, I'm not wearing underwear."
