Beyoncé and Jay Z weren't the only celebrities Britain’s Duke and Duchess of Cambridge met during their stop at the Barclays Center in Brooklyn Monday night. Prince William and Kate Middleton were also greeted by NBA athlete LeBron James after watching him and the Cleveland Cavaliers play the home-team Brooklyn Nets, E! News reports.

The Duke and Duchess, both 32, were reportedly given a Cavaliers jersey by James to bring back to London for their 1-year-old son, HRH Prince George. Similar to the others who have been greeted by the couple during their whirlwind 2014 New York City tour, James, 29, shared his excitement over his meet-and-greet with the royal pair. 

“This very moment will be forever remembered and put up in my house,” James captioned a photo of himself smiling while talking with an equally cheery Prince William and Kate on his “King James” Instagram account. “It’s all good and smiles on this side. #Royalty #StriveForGreatness #RWTW #LRMR #Klutch.”

James later shared a collection of pictures of himself posing with the royal couple and handing over the jersey for Prince George. “Wow, what an honor!” he said. “This game has brought me so much and I’ll never take it for granted!”

Prior to meeting LeBron, Prince William and Kate interacted with music royalty Beyoncé and Jay Z. The two couples reportedly shook hands and had a lively chat during their courtside meetup after the game’s third quarter. The New York Post previously reported that the four were scheduled to meet to discuss a collaboration between the NBA and William’s African wildlife conservation foundation, United for Wildlife.

Before going to the game in Brooklyn Monday night, Kate was in New York City visiting the Northside Child Development Center in Harlem with Mayor Bill de Blasio’s wife, Chirlane McCray, and attending a luncheon at the British Consul General’s Residence. Meanwhile Will was in Washington, D.C., to speak with President Obama about wildlife preservation. He later delivered a speech on the topic at the World Bank’s third Biennial Meeting of the International Corruption Hunters Alliance. 

Prince William and Kate are scheduled to visit the National September 11 Memorial Museum Tuesday. In the evening, the duo will attend a fundraiser for their alma mater, the University of St. Andrews, at the Metropolitan Museum of Art before returning to London.
