Watch | When the Obamas met the Royals for dinner

Obama capped his royal UK visit with a trip to Kensington Palace, where he and the first lady were invited for dinner with Prince William, his wife, Kate, and his brother, Prince Harry. William is second in line to ascend to the throne after his father, Prince Charles. The palace later released a series of photos showing everyone chatting in the drawing room of William and Kate's home, and of Obama kneeling in front of George, who appeared ready for bed in pajamas and a robe. In some photos, a stuffed toy replica of Obama's dog Bo, an earlier gift to the toddler from the president, rested on an ottoman.
