Worlds collided last night at the Barclays Center in Brooklyn. The Nets lost to the Cavaliers, but the fans were thrilled anyway by the presence of the Queen of Pop, the King of Hip Hop, and the Duke and Duchess of York.

Beyonce and Jay Z were sitting courtside, and Prince William and Kate Middleton joined them during the third quarter. Between the third and fourth quarters, the two famous couples met on the court and shook hands while smiling.

Can't you just hear those lovely British accents asking politely, "And what do you do?"
