Rihanna Honored for Leukemia Work

Rihanna isn't the only girl in the world to support the fight against leukemia: Last Thursday, the music superstar joined celebs like Eva Mendes and Leighton Meester at the annual gala for DKMS, an organization that connects bone marrow and stem cell donors with patients in need.

Rihanna (pictured above with DCOO Katharina Harf) received an award for her involvement in the fight against leukemia. "It is the number one disease children in the U.S. die of and we can change that," she said. "If we have more donors, we can save more lives."

DKMS currently hosts the largest bone marrow donor center in the world, with more than 2.7 million donors registered. The gala helped raise money to add nearly 40,000 bone marrow donors, but the DKMS mission doesn't stop there. Adding people to the registry only takes a swab from the inside of your mouth, so host a bone marrow drive and help save the lives of those battling leukemia.
