US President Barack Obama and his wife Michelle, are currently on a state visit to the United Kingdom, and pair paid a high profile visit to two year old Prince George, third in line.
George, elder child of William and Kate, the Duchess of Cambridge, apparently stayed up past his bedtime to greet the Obamas; whilst the newly born Charlotte took her sleep.
The President had earlier met with the Queen and Premier David Cameron, taking a strong stance against the campaign to move Britain out of the EU.
George is third in line to the throne, after his grandfather Charles, The Prince of Wales, and his father, The Duke of Cambridge.
