NEW YORK, June 3 (UPI) -- Singers Rihanna and 50 Cent, and actress Leighton Meester have joined a campaign to help find a bone-marrow donor for a sick New York baby.
The New York Daily News said the celebrities, along with rapper Pharrell and members of the rock band Linkin Park, have had their cheeks swabbed to see if they are matches for Ayelet Galena, a 1-year-old girl suffering from the life-threatening disease dyskeratosis congenita.
