I love Robert De Niro because he is a straight shooter.

I don’t think the dust-up with Jay Z was as bad as they are making it out to be, but still funny nevertheless. Jay Z and De Niro were at Leonardo DiCaprio’s birthday party. When Jay Z went to say hello, De Niro was in the mood to talk, but not about what Jay wanted to talk about.

“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 says.

A spy then overheard De Niro complaining to the rapper, a fellow TriBeCa resident, about a song Jay-Z agreed to record for the Tribeca Film Festival. De Niro had reached out to discuss further details, but Jay never returned his calls.

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

I get the feeling that Jay will be calling today.

And the winner is BOB….
