Cradled in his father's arms, 22-month-old Prince George certainly lived up to his nickname of 'the Prince of Cuteness' when he arrived at the Lindo Wing this afternoon.
Waving at the battery of cameras and smiling shyly, he was en route to meet his new baby sister who made her entrance into the world at 8.34am this morning and will leave hospital tonight.
But it isn't the first time that a royal heir has arrived to visit a newborn sibling in front of the media waiting outside St. Mary's Hospital in Paddington.
They were also there to meet the new royal spare, the newborn Prince Harry who at the time was tucked away in a private room with his mother, Princess Diana.
And the similarities don't end there. With his blonde hair and chubby cheeks, George looks strikingly like to Prince William at the same age - and even wore a similar outfit.
