Stephanie Seymour is one hot, bikini mama – and she’s not bashful about flaunting it!

The 44-year-old supermodel stripped down into a variety of super skimpy and sexy swimsuits over the weekend, flaunting her fabulous figure while frolicking on the beaches of St. Barts with her Rich Kids of Instagram sons – and Breaking Celebrity News has the photos.

Seymour poured her impressive assets into a teeny tiny navy blue bikini and also a black crocheted monokini over the holiday weekend, both which showed off her bombshell booty and boobiful chest to perfection.

By her side almost every second were her three kids from her marriage to billionaire Peter Brant Sr., including her sons Peter Brant II and Harry, who have become fixtures on the popular Rich Kids of Instagram website.

In January 2011, Seymour sparked a media frenzy after photos surfaced of her looking strangely intimate with her son Peter Jr. who later went on to "explain their behavior" by revealing that he is gay.
