While leaving a friend's house in Santa Monica earlier today (March 24), Renee Zellweger flashed a happy face for the cameras despite her recent breakup.

The "Jerry Maguire" actress sported big black sunglasses, a buttoned jacket, ripped blue jeans and sneakers as she continues to reacquaint herself with the single life.

As for the 41-year-old's split with "Hangover" hottie Bradley Cooper, insiders tell that it may have had something to do with a third party after all - his career!

A source close to Cooper said of the speculation of another woman in his life: "If I had to pick any possible mistress it would be Brad's career. He worked really hard to get into leading man status."
