Jay-Z was not having it when a man tried to film Beyonce at Diddy's 50th birthday party. Footage emerged on Sunday of Jay-Z snatching a phone away from a guy's hand. The man looked like he was attempting to record Beyonce, Kelly Rowland, and Saweetie dancing. Although there is a lot of footage leaking from the party, Jay-Z wasn't feeling this guy checking out his wife. Have you ever recorded something on your phone that you weren't supposed to?
