Alicia Keys and Jay-Z are pairing up again.

The "Empire State of Mind" singers announced they will perform at Keep a Child Alive's seventh annual Black Ball event, along with R&B soul singer Sade, in New York this September. The pregnant Keys, 29, co-founded the charity, which provides care to children and families with HIV and AIDS in both Africa and India, in 2003.

Held in New York City, the Black Ball honors humanitarians who have given their time to raise awareness of the AIDS pandemic. Since 2004, the event has raised over $10 million for orphan and clinical care facilities and KCA has helped over 250,000 people.

Keys is thrilled to have the performers on board.

"Sade? Jay-Z? Both icons and both major influences of mine," Keys told in a statement. "I am overwhelmed by their generosity in helping us continue the tradition of making the Black Ball the best fundraiser in NYC."

Previous celebrity guests at the ball include Justin Timberlake, John Mayer, Jennifer Hudson, Sheryl Crow, Bono and Usher.

The event's celebrity host will be announced in the next few weeks.
