Kensington Palace have released the most adorable photos of Prince George meeting President Obama and the First Lady during their UK visit.
The photos show the prince dressed in his white robe thanking the US president for his rocking horse, which he received as a present from the White House when he was born in 2013.
The young prince looked very excited to be staying up past his bedtime to meet the US president.
The pictures were taken after President Obama and the First Lady had dinner at Kensington Palace with the Duke and Duchess and Prince Harry, as part of their four-day UK visit.
