We all know many members of Clooney's ex-girlfriends but do you remember that he used to date Kelly Preston? The two dated from 1987-1989 and lived together long before either one of them was famous and before she became Mrs. John Travolta.
Following Preston was actress Talia Balsam. She is the only woman to ever get George to the altar. After their divorce in 1993 she went on to marry Mad Men's John Slattery and George uttered famous words he'd live to regret.
"It was the first year of ER and I said, 'I'm done,'" Clooney told ET in 2002 about never marrying again. "When you first get famous you don't understand how definitive statements can box you in!"
After his divorce, the actor had a thing for waitresses including Celine Balitran from 1996-1999 and Sarah Larson. He and Sarah met in Vegas in 2007 and by the next year he was parading her down the Oscars red carpet.
"I had to show up with Sarah on a bet," he joked.
Before Sarah, he and English fashion model Lisa Snowdon had an on-and-off relationship for five years after meeting in 2000. But by 2009, we thought he had finally found "the one" in Italian model Elisabetta Canalis. Sadly, the two broke up in 2011.
Finally, there was the actor's two year romance with Stacy Keibler from 2011-2013. After their breakup, we were beginning to think he'd be a playboy forever!
