Rihanna's about to get up close and personal in her campaign with coconut water drink Vita Coco.

The singer told music.aol.com, "I grew up in Barbados -- so when Vita Coco approached me to help develop a new flavor, I thought we should combine the natural coconut with fresh tropical fruits -- two of my favorite things."

The 23-year-old endorses the product along with fellow investors Madonna and Red Hot Chili Peppers frontman Anthony Kiedis.
