It's bikini madness!
All the stars have flocked to warmer climates for the holidays, where many of them are showing off their amazing bikini bodies.
Yesterday, Rihanna looked sexy in a red two-piece in Barbados, Maria Menounous rocked a snakeskin print in South Beach while Kimora Lee Simmons looked amazing in a mismatched top and bottom in St. Bart's.
There's no doubt they all look great -- but, our question to you is, which one of them looks best?
