Former Sports Illustrated Swimsuit Issue & Victoria's Secret catalog model Stephanie Seymour hit the beaches of St. Barth's over the weekend, showing that she's still got a rockin' bikini bod at age 45.

Stephanie spent the day with her husband, industrialist Peter Brant, and their three kids during their annual trip to the Caribbean island.

The model filed for divorce from Brand after 14 years of marriage in 2009, but the couple reconciled in 2010.
