In a celebration that was undoubtedly fit for a prince, the Duke and Duchess of Cambridge, along with George and their two other children, four-year-old Princess Charlotte and one-year-old Prince Louis, marked the special occasion with a family holiday to the Carribean on the private island of Mustique.

The world was first introduced to Prince George Alexander Louis on the steps outside the Lindo Wing of St. Mary's Hospital in London on July 23, 2013.
