Caroline Kennedy Gets Cheeky In A Swimsuit In St. Barts

She looked the part of a serious swimmer in a one piece suit and goggles.

And the exercise certainly has been paying off - she showed off her incredibly lean and muscular physique.

But no beach vacation is complete without some time to sun those buns.

And she did just that with her daughter, 25-year-old Tatiana Schlossberg.

Of course, the hazard of wearing a swim suit is the inevitable beach wedgie!

Caroline currently serves as the U.S. Ambassador to Japan.

And everyone needs some time to blow off steam.
