Oscar winner George Clooney and girlfriend Sarah Larson have called it quits, PEOPLE.com reports.

The couple had been dating for a year before the relationship ended.
A source tells In Touch, "George is relieved to be single again. He thinks Sarah is sweet and that is why it was so hard to break up with her. The truth is that they had little in common and he just doesn't want to be tied down."

Clooney's rep refused to confirm the reports, saying, "We do not comment on George's personal life."
