George Clooney and Stacy Keibler split over the phone.

The 'Argo' actor and the former WWE wrestler made a joint decision to part ways due to conflicting work schedules after over two years of dating, but rather than end their relationship face-to-face they did it during a call.

A source told TMZ: ''Both sides realised there is no way to have a relationship when you don't see each other.''

During the conversation George, 52, repeatedly told Stacy, 33, he wanted to remain friends because that's how their relationship started.

The source added: ''He was very respectful, adult about the situation ... he reminded Stacy that they were friends before they dated and wants to be friends after.''

The couple had grown apart over the last three months, with George in Europe working on a movie and Stacy in Los Angeles working on her new TV show 'Supermarket Superstar'.

As George was due to stay in Berlin, Germany, until December, and Stacy didn't want to spend the next five months seeing the Hollywood heartthrob sporadically.

It has also been claimed the blonde beauty was keen to start a family and have a baby, something George wasn't prepared to commit to.
