Rihanna has been flaunting her bikini body recently on a winter break looking as lovely as ever.
We have her bikini body secret.
Rihanna snacks on pineapple to keep her bum cellulite free - as well as squats and lunges to ensure it stays in shape.
Nutritionist Jeanette Jackson, author of The Drop Zone Diet; Lose 14lbs in 14 days! told Look magazine that pineapple is: "Rich in vitamin C, which creates healthy collagen production to reduce the orange-peel effect of cellulite.
"Plus, it contains bromelain, an enzyme that aids the breakdown of protein and helps tone muscle."
It's time to start snacking on the pineapple then ready for the bikini season.
