I'm not exactly sure what this photographer did to make Bruce Willis flip, but what ever it was, it sure made for amusing entertainment. Splash snapped away as the Die Hard star confronted the pap outside Demi Moore's flat and threatened him. He chased the little guy around with a cheeky smirk, before eventually warning the pap, "Next time stay out of the way or you're going down." I don't know, give an old man a hot girlfriend and he thinks he's the king of the world. Pictures by Splash News
