Molly Sims in a Bikini With Her Son in Miami

Hot Mama! Molly Sims Hits the Beach With Baby Brooks

Molly Sims was all smiles while at the pool in Miami.

Molly Sims flaunted her figure in a bikini on Christmas Eve in Miami Beach, FL. Sporting a black-and-white swimsuit with a hat, she played around in the pool with her young son, Brooks Stuber. Earlier this week, she looked amazing in a printed two-piece while carrying Brooks on the sand. After a whirlwind month of work and play — including a night out at Beyoncé's LA concert — Molly and her family are spending time in Miami for the holidays. She tweeted a photo of herself and little Brooks at the airport last week, saying, "Ready to take off on our Christmas vacation!!!"

Even while indulging in some rest and relaxation on the beach, Molly made time to wish congratulations to her friend and stylist Rachel Zoe on the birth of her second son over the weekend. If our recent interview with Molly is any indication, she could be adding to her own brood, as well — she expressed lots of excitement over wanting "baby number two" very soon!
