Leaving her husband and son to fend for themselves, Stephanie Seymour was back out for another round of fun at the beach on Monday afternoon (December 22).

The sexy supermodel showed off her smoking hot body on Flamands Beach in St. Barthelemy, playing in the sand and surf with her young daughter Lilly.

As previously reported by Fropki.com, Seymour is also accompanied on the French island by her publisher/real estate developer hubby Peter Brant and their son, Harry.

On the career side of things, Stephanie, 40, can next be seen in a top-notch gig as the new face of Valentino's Spring/Summer 2009 campaign.
