Rihanna

R&B singer Rihanna is excited and thankful that the leukemia-stricken mother of two she supported was able to find a bone marrow donor. "There are no words to express how happy I am for Lisa [Gershowitz-Flynn] and her family," Rihanna tells People. "I am so thankful she found a donor and I feel honored to be a part of such an amazing miracle." Last month Singersroom reported that the Barbados star was working with DKMS, an international donor network based in Tubingen, Germany, to try to find a donor for the 41 year old Flynn, who learned she has an aggressive form of cancer called Acute Myelogenous Leukemia the day after Thanksgiving. "This blessing has continued to keep me aware of how precious life really is," says Rihanna. "I will be praying for Lisa and her family as they move into a hopeful future." Flynn is now awaiting a bone marrow transplant. "My life will be saved because of you, my family and friends (old and new)," Flynn wrote in an e-mail to supporters. "My children (Michael, 5, and Alexandra, 3) will have their mother, my husband will have his wife, and my parents will have their daughter. Please continue to spread the word about how important it is to fill the bone marrow registry with donors to save others."
