De Niro, Jay-Z Fight in the Middle of Celeb PartyIt doesn't get much more epic than this: Robert De Niro and Jay-Z had a verbal and physical throwdown at Leonardo DiCaprio's celebrity-filled birthday party, sources tell the New York Post. Sources say the rapper approached the actor at his table to say hello, and De Niro was having none of it. He "told Jay that he never called him back," a source says. Witnesses say the argument had something to do with a song Jay-Z said he would record for the Tribeca Film Festival.

"Bob wasn’t in any mood to make polite conversation," a source says. "He told Jay that if somebody calls you six times, you call them back. It doesn't matter who you are, that is just rude." Jay-Z tried to joke that he's bad on the phone, but De Niro didn't back down and called him "disrespectful" and proceeded to throw Jay a powerful right hand jab reminiscent of his oscar winning role as Jake LaMotta in the film 'Raging Bull'. Even Beyoncé, who tried to intervene, wasn't able to break up the fight and restore the peace. "It was definitely the talk of the party," a source says. "Everyone was saying there’s only one star in New York bigger and badder than Jay-Z, and that's Robert De Niro. He can be quite scary when he's drunk and angry."
