Rhys Ifans ruined his girlfriend's birthday party on Wednesday by embarassing himself in front of the public. The guy was in 29-year old Kimberly Stewart's birthday party when he saw some men closing up to his girlfriend. "F**k off. Don't touch my bird! Let's take this outside, you think you're a big man?" he yelled as they get into a fight. After security broke off the fight, the 40-year old climbed on a table, smashing glasses onto the floor. He was then seen drawing some mustache on his face, claiming that he was a 'big fan' of Hitler. The embarassment continued as he simulated sex on a friend who had fallen on the floor. Eventually, her grilfriend confronted him. She said: "F**king calm down. I've had enough of this s**t, Rhys, don't do this. It's my birthday, stop acting like you're 12," and the two were last seen boarding a taxi. Source: celebrityspotlight
