Go Behind The Scenes Of Rihanna's New Vita Coco Campaign

Looking to shape up for the summer bathing suit season? Maybe take a cue from Rihanna and start sipping on some coconut water. The pop star and Vita Coco spokeswoman tells Us Weekly the electrolyte-heavy drink is the secret to her fab physique.

"I wasn't drinking enough water before, and I love coconut water," RiRi tells the mag. "It hydrates me just as much as regular water so it really started to affect my diet and the way my body was shaping up."

It's a sentiment the "Where Have You Been" singer echoes in a new behind-the-scenes video from the photo shoot for her latest campaign for the brand, which was shot by famed photographer Terry Richardson.

So what's her favorite flavor? "Tropical Fruit Punch … [It] completely dilutes the taste of coconut water, if you're not really into it."
