'Star Trek' star Chris Pine has kept his courtship of Olivia Munn pretty quiet. Fittingly, their breakup is no different. They've been dating since last fall, but the two kept their distance at a pre-Golden Globes party on Friday. A source later confirmed to PEOPLE they've split.

Munn and Pine were spotted two weeks ago looking like lovebirds during a night on the town in L.A.

According to one onlooker, "They looked like they were having a lot of fun. They were really playful, and it seemed like they couldn't stop touching each other."
