Rihanna Helps Olympic Hopeful

Rihanna has become a regular do-gooder. In between promoting her latest album 'Rated R,' posing nearly nude on the cover of GQ and hanging on a yacht with new boyfriend and baseball player Matt Kemp, the R&B/pop diva is trying to find a donor for Olympic hopeful Seun Adebiyi.

Rihanna was moved to help Adebeyi -- who is battling leukemia -- after reading a letter from the Nigerian athlete. The 26-year-old was all set to compete in this year's Olympic Winter Games in Vancouver but his dreams were cut short when he was diagnosed with leukemia during training.

"Leukemia interrupted Seun's dream of being the first Nigerian in the Winter Olympics, but we can help him make his dream come true," Rihanna said in a statement. We need to find him a bone marrow donor! Please sign up with DKMS!"

Adebiyi recently released a statement expressing his gratitude. "I am deeply touched by their plea for donors, not just for me, but for others as well," he said. "Their voices are so powerful and it encourages me how they used their influence to raise awareness about this issue. It was incredible."

This isn't the first time the singer has lent her support to help find donors for those in need. Last year, Rihanna helped 43-year-old Lisa Flynn and six-year-old Jasmina Anema find bone marrow transplants.
