The Keep A Child Alive’s 6th Annual Black Ball went down last night in NYC.  The fab women of the industry came out show stopping, especially Halle Berry. No one rocks a short pixie cut like Halle, and we can't believe she is over 40! Usher was also there to show support to his friend, Alicia Keys, one of the founders of this inspirational and groundbreaking foundation.  Mary J. Blige, Spike Lee, Iman, Kerry Washington, and many more were also in attendance. Pics after the jump.
