Stephanie Seymour & Harry Brant: St. Bart's Vacation!

Stephanie Seymour frolics on the beach in St. Bart’s on Monday (December 26).

Earlier in the week, the 42-year-old former supermodel spent the morning by the pool with her husband, art collector Peter Brant. She later headed into town with her adorable, fashion-obsessed son, Harry.

Harry has been having a lot of fun during his vacation. He tweeted yesterday, “Isn’t it funny how we complain about sleep deprivation during the week and then on vacation were out all night and have it even worse!”
