PHILADELPHIA, PA

Robert De Niro and Jay-Z got into a tense beef at Leonardo DiCaprio’s birthday bash the other night, when De Niro called the rapper disrespectful.  According to Page Six, “Godfather II” and “Taxi Driver” and now “Silver Lining Playbook” star De Niro gave Jay a dressing-down in a roomful of celebs including Martin Scorsese because the rap mogul had refused to return De Niro’s calls.  Jay tried to joke his way out of the situation, and even his wife, Beyoncé, tried to intervene, but De Niro wouldn’t back down.
