It's R&R time for the royal family! Following a whirlwind of public appearances, an expectant Kate Middleton has headed to warmer temps along with Prince William, Prince George, and her parents. The clan is vacationing on the island of Mustique, People reports.

This isn't the first time that the Duke and Duchess of Cambridge have traveled to the tropical isle with their brood—the family typically makes an annual winter excursion to the locale, where they picnic on the beach, swim, and play tennis. This year's trip is extra special in two ways, however. First, Kate's mother, Carole, is celebrating her 60th birthday at the end of the month. And second, Kate and Wills took a pre-baby trip to Mustique prior to Prince George's birth. There's a chance that the next time they visit, they'll be a family of four!
