She's spent the past week parading her incredible bikini body at St. Barts.
And Stephanie Seymour gave spectators a glimpse into some of the fitness behind her enviable figure Saline Beach Wednesday.
Easily defying her 44 years, the former Sports Illustrated model was seen both snorkeling and contorting her perfect body into precise Pilates/yoga poses on the sand.
The brunette bombshell, wearing a black one-piece with spaghetti straps, is said to employ a high-protein diet and a rigorous exercise regime of Pilates, cardio work, and yoga to stay fit.
And as Stephanie seamlessly transitioned from downward facing dog to upward facing dog poses, it's clear she's very disciplined with her exercise routines.
Looking like a real-life Bond girl, Seymour appeared make-up free as she carried her snorkel and flippers.
Her rock star dating past was faintly evident thanks to the dated nineties tattoo surrounding her right ankle.
The five-foot-10 stunner was not alone either, as she was joined by her eight-year-old daughter Lily and 15-year-old son Harry for some fun in the sun.
Not seen Wednesday was the kids' father and Stephanie's longtime husband Peter Brant.
She and the 65-year-old mogul, who's worth an estimated $2.7 billion, have homes in Connecticut, the Hamptons, and Manhattan.
The couple's eldest son, openly gay socialite Peter II, was last seen browsing the men's clothing stores with his famous mother in Gustavia on Sunday.
The flamboyant teen caused a bit of controversy two years ago in the Caribbean hot-spot for embracing and kissing his bikini-clad mother on the mouth and brushing his hand over her breast.
