Jennifer Hudson brought the house down for a good cause. The Grammy-winning singer lent her powerful pipes to Russell Simmons’ 12th Annual Art for Life Benefit at the music mogul’s estate in the Hamptons on Saturday. The Def Jam founder was joined by his ex-wife Kimora Lee Simmons, brothers Rev Run and Danny Simmons, nieces Angela and Vanessa Simmons, and the rest of his family. VIPs including Mary J. Blige, Taraji P. Henson, and L.A. Reid bid on unique items to help raise money for his non-profit organization and Miri Ben-Ari entertained guests by playing the violin.
