Jay-Z, Warren Buffet At The 40/40 Club: Rapper, Billionaire Hang Out (PHOTO)

Here's a question: who pays the tab when these two hang out?

Jay-Z reopened his 40/40 club in New York City on Wednesday, and joining him at the hot event was billionaire investor and philanthropist Warren Buffett. The two are friends, having traded appearances in cartoons and magazine interviews, and clearly were enjoying themselves, joking like the global icons they are.

Hard to say what they were talking about; maybe it was the finer points of fatherhood, or perhaps their willingness to pay more in taxes.
