Rihanna campaigns to save girl's life

Rihanna, 50 Cent and other celebrities have joined a campaign to help save the life of a terminally ill baby girl.

Ayelet Galena, 1, suffers from a rare congenital disorder and requires a bone marrow transplant in order to survive.

50 Cent followed Rihanna in getting a blood test to see if they could be potential donors for the baby girl.

Rihanna later tweeted to her followers to offer their help, saying: "Can you help me find a lifesaver for baby Ayelet and other patients? Get swabbed (tested) because maybe you can save a life!"

Leighton Meester, Linkin Park and Pharrell Williams have also lent their support by highlighting Galena's illness.

Rihanna had previously lent her support to six-year-old leukaemia sufferer Jasmina Anema, who passed away in January.
