27 December 2012     
She's spent the past week parading her incredible bikini body at St. Barts.

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.

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.
