The stars were out in full force tonight to attend the Alicia Keys-hosted 8th annual ‘Keep A Child Alive’ Black Ball, held at New York’s Hammerstein Ballroom.  The star studded event, with previous years’ guest lists boasting names like Whitney Houston, Beyonce, and more, included appearances and performances from the likes of Will.I.am, Tyra Banks, Serena Williams, Mary J. Blige, Usher, and Mrs. Beatz herself (among others).

This year’s ‘Ball’, which honored late Beatle George Harrison, benefits Keys’ Keep A Child Alive foundation.  See more photos below:
