The Duke and Duchess of Cambridge meet Beyonce and Jay-Z The Duke and Duchess of Cambridge meet Beyonce and Jay-Z

The Brooklyn Nets game Monday night became a royal affair when Prince William andKate Middleton hung out courtside with America's reigning couple, Beyonce and Jay Z.

In between the third and fourth quarter, Bey and Jay walked across the court to Will and Kate's seats, where they chatted for a few minutes.

The Duke and Duchess also met a "King" that night, when they got a private meeting with LeBron James after the game. The Cleveland Cavaliers star even gave the couple a mini jersey for their son George. However, James majorly broke royal etiquette when he placed his arm around Kate's shoulder during a photo op.

Her reaction = priceless.
