Rihanna & Justin Chambers Fight Leukemia

Rihanna and Grey’s Anatomy star Justin Chambers are stepping up to help a 26-year-old winter Olympic hopeful find a life-saving donor match. Seun Adebiyi, a Nigerian Yale Law School Graduate was training for the 2014 Olympic Winter Games when he was diagnosed with Leukemia.

When Rihanna, who made a public plea last year to help 6-year-old Jasmina Anema find a match, received a letter from Seun, she was so moved by his plight that she joined his mission to recruit 10,000 donors with DKMS, the world’s largest bone marrow donor center. “Leukemia interrupted Seun‘s dream of being the first Nigerian in the Winter Olympics. But together we can help him make his dream come true! We need to find him a bone marrow donor! Please sign up with DKMS,” said Rihanna.

Similarly, Justin recorded a PSA for DKMS last month between takes on the Grey’s set, urging minorities to donate. Watch both Justin and Seun‘s PSAs below!
