Sounds like it's the old 2 year itch for George Clooney and Stacy Keibler. Sources close to the couple say the pair has ended their relationship. According the UK's Sunday People, it was George who pulled the plug on their relationship and that he's been backing away from it for some time now. But, a friend of Stacy's tells People Magazine that it was her who ended things because she wants to have a family someday and she knows where George stands on that. However, additional sources say it's not true and the pair is still together. Send us a tweet and let us know what you think!
