The ONE person I thought would never have a rap beef is Robert De Niro. Turns out, I was wrong. 

Bobby still has some bad feelings towards Jay-Z over an agreement from years ago. Hov' (born Shawn Carter) had agreed to do a song for the Tribeca Film Festival and never did it. De Niro called him on it at Leonardo DiCaprio's birthday party from the weekend. De Niro said "if someone calls you six times, you call them back".

Jay-Z tried laughing the situation off but De Niro wasn't having it. "I think you're the man, but that's disrespectful" he stated.

Hmmmm. This seems a bit odd, but I think Jay's the people's champ so we might have to agree with him on this.
