Caroline Kennedy and her husband Edwin Schlossberg were snapped on the beaches of St. Barth, and she may be 55, but she looks incredible!

Kennedy is rumored to be the next U.S. ambassador to Japan, and not only has she been gearing up for that role, but she's also set to promote her new book next month, Poems to Learn by Heart, which is a collection of more than 100 poems that she has selected. Kennedy is the honorary chair of National Library Week and the president of the JFK Library Foundation, and she's also a member of the John F. Kennedy Profile in Courage Award selection committee. Whew ... She sounds pretty busy!

Hopefully not too busy to notice that she was falling out of her swimsuit though ... eeks!
