On Friday, President Barack Obama and First Lady Michelle Obama [1] hopped across the pond to the United Kingdom, where they spent time with the British royal family [2]. President Obama may primarily be in town for a press conference with British Prime Minister David Cameron, but he still made time for dinner at Kensington Palace. Suffice it to say, seeing the Obamas with Prince William and Kate Middleton is exciting enough. The official Twitter account for Kensington Palace [3], though, did us one better when it shared adorable new pictures of Prince George! In the snaps, the little lad stops in for a meet-and-greet with the president and his wife, wearing none other than his pajamas. It's just the icing on the cake for all the cuteness overload from this week . . . not that we're complaining. Just in time for the queen's 90th birthday, George also posed for a new set of British stamps [4] and even appeared in a new royal portrait [5]. Keep reading to see his pajama party with the Obamas.
