According to the New York Post’s Page Six column, things allegedly got pretty heated between Hip Hop mogul Jay-Z and actor Robert De Niro during a birthday celebration for Leonardo DiCaprio.

The confrontation between the two stemmed from various phone calls De Niro made to Jay-Z that went unanswered. The actor was hoping to discuss a song Jay-Z was to record for the annual Tribeca Film Festival.

“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 revealed to the New York Post.

“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,” another source added.

Those in attendance at the birthday celebration revealed that the confrontation between the two men reportedly reached a point where even Beyonce had to intervene.

Reps for both Jay-Z and De Niro have chosen not to comment on the incident.
