Jay-Z, Beyonce, Usher Support Alicia Keys At AIDS Charity Ball

Jay, Janelle Monae, Swizz Beatz were among performers at Keys' 8th annual Keep a Child Alive event.

Alicia Keys has proven to be as selfless in real life as she is in song.

The singer held her 8th annual Keep a Child Alive Black Ball event in New York on Thursday night. The fundraiser brought out Jay-Z, Beyoncé, Usher, Jay Sean, Janelle Monae, Jennifer Hudson, Whitney Houston and more.

Jay-Z and Keys' husband, Swizz Beatz, performed "On to the Next One," and Jay later performed "Empire State of Mind." Monae also hit the stage, as did Keys and Sade, who performed a duet, "Love Is Stronger Than Pride."

"It's my heart and soul," Keys told MTV News about the organization she co-founded. "Since the beginning, we've been very driven to do incredible work. I'm proud to show what four to five women who are very dedicated can do."

The organization benefits children and families who have been affected by AIDS but can't afford to purchase medicine; the event reportedly helped raise $2.4 million.

This year, Keep a Child Alive introduced the "Buy Life" T-shirt. The shirt features a large barcode on the garment; donors can buy the shirt and scan the code with their smart phones to make a donation to the charity. Every time the code is scanned by a phone, a donation goes through. Ryan Seacrest, Kim Kardashian and Katie Holmes are among the celebrity spokespeople appearing in ads for the shirt.

"It's like a dream to me to be among these people singing and performing, and opening people's eyes to what Keep a Child Alive can do," Keys said.
