Kate Middleton and Prince William became courtside witnesses for the game between the Brooklyn Nets vs. Cleveland Cavaliers, on Dec 8, Monday.

The pregnant Middleton and her Prince Charming walked down to their seats seven minutes into the third quarter. When spectators saw the royals, they got a standing ovation and fans kept taking pictures instead of watching the game.

The 2nd-in-line to the British throne was seen wearing a casual plaid-button shirt seated next to Dikembe Mutombo, a retired NBA player, who further explains the game to him. Middleton, on the other hand, wore a skinny jeans donned in a Tory Burch tweed coat.

Jay and Bey walked across the court to meet the royals, while "God Save the Queen" and "Crazy in Love" blasted from the big speakers.

Prince George will soon receive his little jersey, courtesy of Lebron James and Kevin Garnett, as they gifted the young prince a tiny memento of the NBA.

Earlier on the day, Prince William met with US President Barack Obama at the White House. The two powerful people even joked around and this marks the Prince's first visit to the Oval Office. He then gave a speech at the World Bank anti-corruption conference.

Flying back to New York to be reunited with Middleton, the couple attended a reception at the British Consul General's residence to recognize the work of The Tusk Trust and other partners of William's charity United for Wildlife.

The Princess, on the other hand, spoke with potential presidential candidate Hilary Clinton about the benefits of singing to babies and her visit earlier in the day to a children's center in Harlem.

The Royal couple then finished the day with an NBA game.
