It went down this way. Jay-Z sauntered up to De Niro's table to say hi, apparently having forgotten about the six phone calls from De Niro about a song Jay-Z was supposed to record for the Tribeca Film Festival. But De Niro...he hadn't forgotten. De Niro NEVER FORGETS. A Page 6 spy described the confrontation. "[De Niro] 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 tried smoothing things over with a joke but Bob wasn't placated. Things got so tense that Beyonce had to step in but even her presence couldn't cool Bob's jets. The Page 6 spy said, "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."
Oh I see what the deal is. De Niro was the king of New York but then Jay-Z came along. So De Niro decides he's going to dress this kid down and show everyone that he's still the boss. Good play De Niro. Now it's Jay-Z's turn. Can you say "scathing diss tracks?" Jay-Z's entire next album will be nothing but songs about what a punk De Niro is. You think Taylor Swift is hard and unforgiving. Try getting under Jay-Z's skin. That guy has more to him than Rosie O'Donnell with PMS. Evidently so does De Niro.
