Stephanie Seymour In A Bikini: Model Shows Off Sunburn

Super-mother Stephanie Seymour, 42, showed she still has her model's body on a beach vacation with her husband and children in the exclusive resort of St. Bart's.

Pictures show the relaxed model (who had some redness and tan lines on her back from not enough sunscreen) frolicking in the surf with her family. She even shared a kiss with her billionaire husband -- Peter Brant, 63 -- with whom she was involved in a bitter divorce battle only a year ago.
