But where's his ladylove Renee Zellweger? And how come he looks so happy without her! Bradley Cooper showed off his pearly whites while visiting a friend in Santa Monica on Tuesday - the hunky actor begins filming The Hangover 2 on October 15th. I know it was just a rumor that Renee herself wanted in, but seriously, do you think Bradley would actually want her on set 24/7?

Never mix business with pleasure! Even Jen Garner told the ladies on The View yesterday that she'd never want to work with hubby Ben Affleck.
