As part of their whirlwind visit to the US, the royal couple made a courtside appearance at the Brooklyn Nets v Cleveland Cavaliers game at the Barclays Centre on Monday night (8 December).
And, as Jay Z is a former part owner of the Nets, it's no surprise that he and wife Beyoncé were first in line to greet the royals!
William and Kate, who is five months pregnant, were pictured deep in conversation with Jay and Bey between the third and fourth quarters of the game.
According to Us Weekly, as the couples met, the songs 'God Save The Queen' and 'Crazy In Love' were blasted around the Barclays Centre.
We imagine they all had a giggle at that…
Kate, 32, looked beautiful in skinny jeans and a tweed coat, while William, also 32, was off duty in a checked shirt and dark trousers.
The second-in-line to the throne was pictured accepting popcorn from a vendor on the floor and pointing out various things to his pregnant wife throughout the NBA game.
William and Kate had spent the day apart, with Kate remaining in New York to meet with the city's First Lady, Chirlane McCray, and visit a child development centre in Harlem, and William jetting to Washington DC to meet with US President Obama and give a speech on curbing illegal wildlife trade.
They are travelling without son Prince George.
William and Kate were at the NBA game as part of the partnership between The Royal Foundation's United For Wildlife and Coach Core programmes, and the NBA Cares global responsibility scheme.
The partnership aims to raise awareness about the importance of wildlife conservation, as well as growing the game of basketball around the world.
