Prince William and Kate Middleton’s Monday evening in New York was spent courtside at the Brooklyn Nets game against the Cleveland Cavaliers.

Prince William Kate Middleton At NBA Game

The Duke and Duchess of Cambridge, as part of their three days in New York City, attended an NBA game in part to launch a collaboration between The Royal Foundation, United for Wildlife and the professional sports organization. For the sporting event, Kate kept it simple in a Tory Birch coat and black skinny jeans, while Will traded in his suit for a plaid shirt and slacks.

Upon arriving at the event, Jay Z and Beyoncé crossed the court to greet Will and Kate, who sat next to former NBA great Dikembe Mutombo. Following the game, the married pair, who are expecting their second child together in a few months, posed for pictures with Cleveland Cavaliers star LeBron James. James, who said it would be a “huge honor” to play before the royals in the days leading up to the game, took to Instagram with pictures of the momentous meeting.

Wow what an Honor! This game has brought me so much and I’ll never take it for granted! The King, “Duke & Duchess. #Royalty #StriveForGreatness #RWTW #LRMR #Klutch
