George Clooney & Stacy Keibler Split

After weeks of speculation about whether George Clooney and Stacy Keibler had called it quits, ET can confirm that the couple has indeed ended their two-year relationship.

A source close to the couple tells ET that the split happened two weeks ago, but that contrary to some reports, the breakup did not happen because Keibler wanted to get married and have children. The source added that the split is amicable and Keibler is now going to be focusing on her career.

Split rumors were sparked when Clooney, 52, and Keibler, 33, began spending a lot of time apart in recent months. The pair celebrated last week's Fourth of July holiday separately and were last photographed together in March in Berlin, Germany, where Clooney was filming on location for his upcoming war drama The Monuments Men.
