Madonna, Rihanna Team Up for Coconut Water Campaign

Madonna and Rihanna are the latest superstar divas to team up for a new project -- but instead of working together on a new single or remix, the pair has joined forces to sell coconut water.

The Vita Coco brand of coconut water, of which Madonna is an investor, will feature the Barbados-born Rihanna in its national advertising campaign launching this summer.

"Rihanna is a natural fit for the Vita Coco brand and I'm so happy to have her on the team," says Madonna in a statement. Rihanna adds, "I love Vita Coco! It's real coconut water from hand-picked coconuts. It's delicious and so good for you!"

Rihanna recently paired with another pop star, Britney Spears, for the remix to her hit single "S&M," while the music video to "California King Bed" premiered on Monday (May 9). Meanwhile, Madonna is completing work on the feature-length film "W.E.," which she directed, due out later this year.
