Well, at least nothing needs annulling this time.
The breakup news hits just four days after Cooper told Howard Stern, when quizzed about his relationship, that he had no immediate engagement plans. Coincidence?
It was always a coincidence that these two found each other, anyway, considering both split with their former spouses in the blink of an eye.
Jennifer Esposito filed for divorce from Cooper after four months in 2007, and Zellweger had her flash-in-the-pan marriage to Kenny Chesney annulled after four months in 2005.
The Case 39 costars still seemed close in January, with Zellweger skipping the Golden Globes to be with Cooper's family in Pennsylvania following the death of his father.
Last month, however, they attended the same pre-Oscar party and were spotted not hanging out together.
Things first looked hot and heavy between them in August 2009, when they were photographed smooching in Spain. Despite the occasional paparazzi pic, the couple played it close to the vest and refused to comment in detail about each other in public.
"I just can't," Cooper told Details last summer when pressed to talk about Zellweger.
