George Clooney and Sarah Larson are Splitsville. The Oscar-nominated actor has called it quits with former cocktail waitress Sarah Larson after almost one year of dating.

George, 47, and Sarah, 29, met in Las Vegas four years ago when the bubbly brunette was working at The Whiskey Bar where George was grabbing a few drinks.

“He thinks Sarah is sweet and that is why it was so hard to break up with her,” a spy reveals to In Touch Weekly.

It wasn’t until last June that the friends decided to take their relationship to the next level and officially began dating. Sarah, a one-time contestant on the defunct NBC reality series Fear Factor, sat down for a gushing interview about her relationship with the dashing Mr. Clooney in the June 2008 issue of Harper’s Bazaar.
