Chris Pine & Olivia Munn Split

Chris Pine and Olivia Munn have split up, JustJared.com can confirm.

After just five months together, the Star Trek star and host of G4′s Attack of the Show (both 29) called it quits on Saturday night, January 16, the night before the 2010 Golden Globe Awards.

“Olivia broke things off with Chris because they just didn’t see eye to eye anymore,” a source reveals to JustJared.com. “Even though he was sweet and charming at the beginning, his personality became too much to handle in the end.”

The two did attend Friday’s NY Times Style Magazine‘s Globes cocktail party at the Chateau Marmont penthouse in West Hollywood but kept their distance.
