Kate Middleton's parents, Carole and Michael Middleton, have jetted off to the island of Mustique to join their royal daughter and the family for a huge blowout bash celebrating Carole's 60th birthday (which is actually on January 31).

E! News learned that a party will be thrown in Carole's honor at one of the private Island's most jaw-dropping properties, Villa Rocina.


Aside from Kate, son-in-law Prince William and grandson Prince George, Carole has invited 30 friends to join for the event, which will also include a signature cocktail for the birthday girl and a "mocktail" for the expecting Duchess of Cambridge.
