One hot mama!
Kimora Lee Simmons, 38, slipped into a two-piece while vacationing in St. Barts with her kids Kenzo, Aoki and Ming, her ex-husband Russell Simmons and her new boyfriend.
That's one very modern family vacation, right?
Aoki and Ming are Kimora's kids with the hip-hop mogul, while Kenzo is her son with ex Djimon Hounsou.
The family is staying on an incredible yacht during their St. Barts stay -- with Kimora tweeting out a photo of the impressive boat on her Twitter page.
She's not the only celeb spending her holidays in the sun. Cindy Crawford, Sofia Vergara and Molly Sims have all been frolicking in the sand -- check out their bikini pics in the gallery above!
