Rihanna's UNICEF Tap Project

Doing what she can to help the less fortunate, Rihanna recently participated in the latest Unicef Tap Project.

The endeavor began in New York City, with a goal of bringing clean and accessible tap water to kids around the world.

At the beginning of this year, Hollywood stars began donating their own tap water in order to raise awareness of the world water crisis.

Other celebs to join Rihanna in the generous effort include Selena Gomez, Taylor Swift, Robin Williams, and Adrian Grenier.
