"It was very special and fun short holiday for the family, and they are grateful that John Stillwell [The PA photographer] was able to capture the moment so well." Photo: John Stillwell

During their meeting, George got on the rocking horse Barack presented to his family in honor of his birth in 2013. The President admitted that he had only one purpose on his trip to London, and he fulfilled it that evening. "I guess you all know why I came this week. It's no secret," he said during a speech in London. "Nothing was going to stop me wishing happy birthday to Her Majesty, or meeting George, who was adorable."

Ready to fly! Before celebrating his third birthday, Prince George embarked on his first royal engagement in the UK. The Prince, along with his parents William and Kate, attended the Royal International Air Tattoo at RAF Fairford in Gloucestershire. George, who was a bit overwhelmed upon his arrival, got comfortable and right at home as he suited up in noise defenders and checked out various planes and helicopters. George was so eager upon his visit that when he was inside one of the AF Aerobatic Team's Red Arrow Hawks with his mom and pilot dad, he asked, "Mummy, can I fly the Red Arrow now?" As William gently told him, "Not right now." Photo: Chris Jackson/Getty Images

Like any royal in training, George was lifted up by his mom to give the crowd a friendly wave while he was inside the cockpit of a plane. Photo: Samir Hussein/WireImage
