Prince George, the third in line for the British throne, turns five today. To celebrate the special occasion, Kate Middleton and Prince William have flown to the beautiful serene beaches of Mustique. This will be their first vacation as a family of five— Prince George, Princess Charlotte and Prince Louis.

The Duke and Duchess of Cambridge are also accompanied by Kate's family—including her parents Carole and Michael. It is believed that the future king will have a grand birthday bash on the islands. George is also expected to try his hands on swimming on the Caribbean beaches.

As George turns five, here we bring you five cutest pictures of the royal heir.

Who can forget George's adorable christening pictures accompanied by his doting parents, William and Kate. The ceremony took place days after the world saw the first glimpse of the royal heir in July 2013.
