Inside Bradley Cooper's Relationship History

Bradley Cooper first met Renée Zellweger in 2006 on the set of the horror movie "Case 39," but the pair didn't get together until three years later. However, it looks like the couple wanted to make up for lost time, as things got serious pretty quickly. In December 2009, the "Bridget Jones Diary" actress spent Christmas with Cooper's family and reportedly moved into his $4.7 million home. Zellweger appeared to be close with his family — she was spotted shopping with his mother in 2010 and missed the 2011 Golden Globes to be by Cooper's side after his father died.

The couple gushed about each other while promoting their film in 2010. "I can't say enough about her. I never met her before this, but I just love her. I love coming to work. I love acting with her. I can learn so much from her," Cooper told Entertainment Tonight. Zellweger returned the praise, saying, "He's a great, great actor. I just got so excited, not believing that I was going to go to work with him."

In March 2011, the couple called it quits after two years together. According to Us Weekly, the split happened because Cooper was too focused on his career. "If I had to pick any possible mistress it would be Brad's career," said a source. "He worked really hard to get into leading man status." At the time, Cooper's film "Limitless" had just nabbed the top spot at the box office.
