Now that George Clooney and Stacy Keibler have split, it’s time to start speculating about what happened between the Oscar winning actor and the model. Reports suggest that it’s been months since they were together and that they broke up over the phone.

There were conflicting reports over the weekend on who actually ended the relationship. A source for People claimed it was Keibler, while the Daily Mail suggested it was Clooney’s doing.

A new TMZ report suggests that it was a mutual decision that a long-distance relationship wasn’t working. Clooney has been in Europe working on The Monuments Men while Keibler is in Los angeles working on a TV show. So they spoke over the phone and “Both sides realized there is no way to have a relationship when you don't see each other,” a source for TMZ said. “He was very respectful, adult about the situation ... he reminded Stacey that they were friends before they dated and wants to be friends after.”

TMZ also claims that reports that Clooney didn’t want children but Keibler did are not true.

Us Weekly’s source said that they “hadn't had sex in months.” Another source explained, “She knew he wasn't looking to get married. But there was always that fantasy that he would commit. Sadly, it just ran its course.”

Keibler is shooting Supermarket Superstar, while Clooney is scheduled to continue shooting in Berlin through the fall.
