Prince William and Kate Middleton: Babymoon Time!

Pregnant Kate Middleton and Prince William have escaped dreary, winter London for a babymoon holiday on the ultra-exclusive Carribean island of Mustique.

Expecting their first child together, the Duchess, 31, and Duke, 30, are kicking back in a luxury villa with a $30,000-a-week price tag - with her folks!

The babymoon is a family affair, apparently. The couple flew out a few days ago to join Kate Middleton's parents, Carole and Michael Middleton.

With Kate completely recovered from the acute morning sickness that plagued the earliest days of her pregnancy, the twosome are ready to party.

Well, within reason. She's still carrying the royal heir(ess).

But with Kate Middleton's due date in July, and her health improved dramatically in the past few weeks, she's earned a nice, fun babymoon vacation!

Not to mention some much-needed family time.

As long as there's no repeat of topless photos that surfaced from their holiday in France - which we doubt, on the secluded island - all is well!
