Rihanna and Michael Clinton (of Hearst Magazines) were honored for their charity work in the fight against leukemia at the 5th Annual Gala for DKMS, the largest bone marrow donor center. The black-tie gala, tonite at Cipriani’s in the Financial District, was hosted by DKMS’ Katherina Harf and featured Pharrell (as master of ceremony), Mary J. Blige, and a special performance by “The Lion King” in honor of Shannon Tavarez, the 11-year-old castmember who died last year of leukemia. Attendees tell me there wasn’t a dry eye in the house during that part, as well as when a donor and patient were reunited on stage. Check out Rihanna, Pharrell, Iman, Solange, Leighton Meester and more in their black-tie finery….
