Rihanna Chosen as New Face of Vita Coco

She's all about keeping a healthy physique, so it's no wonder Rihanna has been picked as the new face of Vita Coco.

The red-headed "S&M" chick posed for pictures on the beach awhile back clad in a gorgeous white get-up for the upcoming ads promoting the nutritious  drink.

Rihanna joins "Material Girl" Madonna as an endorser for the water who told press, "Rihanna is a natural fit the Vita Coco brand and I'm so happy to have her on the team."

Showing her love for the product, RiRi declared, "I love Vita Coco! It's real coconut water from hand-picked coconuts. It's delicious and so good for you!"

The 23-year-old singer has been keeping the fire going on her red-hot career, releasing the artwork for her new single "Man Down" yesterday (May 11).

The "Russian Roulette" babe looks super sexy on the cover shot, the perfect complement to her new tune.

According to omg!, RiRi currently leads this year's Billboard ranks with 18 nominations, including Top Artist, Top Female Artist and Top R&B artist.

Finally finished up with her Nivea brand ambassador duties, the red-headed songstress was spotted departing Hamburg, Germany on Monday (May 9).

Looking glamorous, Rihanna deboarded the Mein Schiff 2 cruise ship at Hamburg's port following a performance aboard the vessel while celebrating Nivea's 100th anniversary.

Having also just released her "California King Bed" music video earlier the same day, RiRi tweeted of her just-dropped video and schedule to make her way back to the U.S., writing, "Homeward bound!!!!! Glad u love #CKBvideo."

Opting to spend the weekend in the City of Lights after performing at a handful of European Nivea anniversary celebrations, Rihanna was spotted leaving her Paris hotel on Sunday afternoon (May 8).

The singer stopped to greet fans as she was loaded into a car to cruise around the French capital city while clad in a cute sheer black jumper with her red locks in a long single braid.

The outing comes just as it was announced that RiRi has been slated to kickoff the "Today" show's 2011 Summer Concert Series.

With the 23-year-old set to take the stage on May 27th, the show also granted a slot to Rihanna's ex-beau, Chris Brown, who will perform on July  15th.
