It's over for Renée Zellweger
and Bradley Cooper
Cooper, 36, and Zellweger, 41, who moved in together last fall to become one of Hollywood's most glamorous couples, have broken up, sources tell PEOPLE.
Although the pair never officially confirmed their relationship, they were frequently spotted out together and Cooper has been vocal about his feelings.
"I can't say enough about her," he said
in September while promoting the couple's film Case 39
. "I just love her. I [loved] coming to work. I love acting with her. I can learn so much from her."
Zellweger even skipped the Golden Globes in January at the last minute to be with Cooper when his father died
. She was also close
to Cooper's mom, Gloria.
But in February, there was speculation about their relationship when they each attended a pre-Oscar party but didn’t hang out together.
Their reps have no comment.
