Robert Pattinson has bar fight over Kristen Stewart?

Robert Pattinson reportedly got into a bar fight standing up for rumoured girlfriend Kristen Stewart.

US Weekly reported that after actor Jason Statham hit on girlfriend Kristen at an LA bar, Rob stepped in.

“Jason is totally jacked and Rob is scrawny,” a pal said. “But Rob said, ‘I think you’ve had enough time with her.’ They got heated.”

Bouncers reportedly stepped in before things got out of control.

According to Hollywoodlife.com, Jason is dating model and Transformers actress Rosie Huntington Whiteley, who some say may have left the star for Shia LeBeouf.

Sounds less like a bar fight, more like a little disagreement?
