Robert De Niro picked a fight with Jay-Z

OHMYGOSSIP — Robert De Niro is a brave man — he allegedly picked a fight with Jay-Z last weekend! The actor called the rap mogul out for being disrespectful in front of a collection of A-list guests including Martin Scorsese and Cameron Diaz at Leonardo DiCaprio‘s 38th birthday party, accusing the music mogul of never returning his calls.

“Bob was sitting at a table, and when Jay-Z went over to say hello, De Niro told Jay that he never called him back,” a source told New York Post gossip column Page Six.

“Bob wasn’t in any mood to make polite conversation. 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.”

The argument was over a song Jay-Z had agreed to record for the Tribeca Film Festival, but the superstar rapper never got back to fellow Tribeca resident Robert with details about the track.

Jay-Z’s wife Beyonce Knowles attempted to diffuse the situation, but onlookers were amazed to see “scary” Robert put the rap star in his place.

“When Jay-Z tried to make a joke of it, saying he is terrible on the phone, De Niro kept telling him that he thinks he’s the man, but that he was disrespectful,” said the source.

“Beyonce came over, but that didn’t calm Bob down. It was the talk of the party. 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 angry.”
