Although the pair had been seen together frequently, neither ever confirmed their relationship in interviews, although Cooper, 36, did praise Zellweger, 41, while promoting Case 39. "I can't say enough about her," he said. "I just love her. I [loved] coming to work. I love acting with her. I can learn so much from her."
In January, when Cooper's father died, Zellweger pulled out of the Golden Globe awards, where she was scheduled to present, to be with him.
Cooper currently stars in Limitless, about a writer who discovers a drug that gives him super-human abilities.
