(showbizspy.com) - Caring pop star Rihanna is trying to help a mum-of-two who could soon die without a marrow transplant.
The 'Umbrella' star is trying to raise publicity to find a suitable donor for Lisa Gershowitz Flynn, who is suffering from an aggressive form of cancer called Acute Myelogenous Leukemia and may have just a month to live.
"When I heard about Lisa's plight, my heart broke," Rihanna said. "I said, 'I need to get the word out about Lisa right away.' "
Rihanna is working with DKMS - the world's largest non-profit marrow donor center to help raise awareness for the need for people to come forward to become donors.
"I think DKMS is an incredible charity because you can really see the results," says Rihanna, who performed at the DKMS Linked Against Leukemia gala last May for free.
She adds: "My own charity, Believe, works specifically with children in need. Children need their mothers more than anything else in the world.
"Lisa has two children. My charity will continue to work with DKMS, because in finding a way to save Lisa's life, we will in turn be saving her children's lives."
Flynn, 41, is blown away that Rihanna is taking time to try to find a donor match for her and countless others who may die if they don't get one.
"For Rihanna to even be thinking about helping others and putting herself out there when she is so busy with her career is tremendous," says Flynn, the mother of Michael, 5, and Alexandra, 3.
A special website has been set up to raise publicity - GiftforLisa.com.
