Alicia Keys, Jay-Z and Sade will all grace the stage at the seventh annual Black Ball NY at New York City's Hammerstein Ballroom. The event, which is mounted by Keys' Keep a Child Alive organization, will take place September 30.

"Sade? Jay-Z? Both icons and both major influences of mine. I am overwhelmed by their generosity in helping us continue the tradition of making the Black Ball the best fundraiser in NYC," Keys said in a statement. "There are more surprises coming up! Stay tuned!"

KCA also organized the Black Ball London this past May, where U.K. group Kasabian and British singer Bryan Ferry performed. The organization helps families struggling with HIV/AIDS throughout India and Africa and, since 2004, has generated more than $10 million. Keys co-founded KCA in 2003, and since then, the organization has assisted more than 250,000 people. KCA also provides financial support to orphan care and clinical centers in countries such as Rwanda and Uganda.

Last year's Black Ball in New York drew 1,000 guests, raised more than $2 million and was co-hosted by Keys, "Top Chef" host Padma Lakshmi and supermodel and entrepreneur Iman. The fundraiser was also held at Hammerstein Ballroom and honored former President Bill Clinton, Virgin boss Sir Richard Branson and Senegalese legend Youssou N'Dour for their work fighting poverty and HIV/AIDS. Keys, N'Dour, John Mayer and Coldplay's Chris Martin performed. A range of celebs, such as Halle Berry, Mary J. Blige, Swizz Beatz, Nick Cannon, David Bowie, Spike Lee and Usher, came out to support the cause.
