Thursday night, a star-studded DKMS 5th Annual Gala raised a record $2.5 million to aid the fight against leukemia and other blood-related cancers.
Pharrell Williams emceed the black-tie NYC event, which included a performance by Mary J. Blige. Stylistas Eva Mendes, Leighton Meester, Rihanna, Keri Hilson, Iman and Solange Knowles also attended.
Rihanna, demure in a black gown and Chopard jewelry, received an award from Katharina Harf, COO of DKMS Americas, for her tireless work in the fight against leukemia.
