The visit of US President Barack Obama and his wife Michelle is an important one since the Queen is celebrating her historic 90th birthday. The two visited Windsor Castle which is outside of London, in order to attend a birthday lunch for Her Majesty.

After which they went to Kensington Palace for a private dinner with the Duke and Duchess of Cambridge, as well as Prince Harry. It was there that they met three year-old Prince George who was allowed to stay up 15 minutes past his bedtime in order to greet the Obamas.

Photos later showed the group talking amiably in an elegantly decorated sitting room. There were some photos of George as well, looking adorable in his pajamas and a white robe. George was shown sitting on the rocking chair that the First Family gave him when he was born. A fluffy Portuguese Water Dog which resembles Bo, the White House dog, can be seen on the center table as well.

The most adorable moment though, came when Obama and Prince William went down to George's level and was seen talking to the future British heir of the throne. It all looked so serious, though we're pretty sure George doesn't even quite know the significance of this meeting.
