Holy royal cuteness!

Prince William and Kate Middleton took Prince George and Princess Charlotte on their first ski vacation, but they managed to keep the getaway completely private until after it was already over! Usually a group of photographers is invited to capture these kind of outings, but the famous family decided to only invite one shutterbug along and keep the location of their destination in the French Alps secret.

"The Duke and Duchess of Cambridge are delighted to share new photographs of their family. The images show Their Royal Highnesses enjoying a short skiing holiday with their children in the French Alps. This was their first holiday as a family of four and the first time either of the children had played in the snow. 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. The Duke and Duchess hope people enjoy the photos," the Palace explained with the released images.

We can't believe how big these heirs to the throne are getting! Little Char even has two teeth coming in!
