Jay-Z performed to a jam-packed Madison Square Garden on Friday night for his benefit concert to support the New York Police and Fire Widows and Children's Benefit Fund.

Tickets for the concert were $50 and sold out in minutes. The crowd, as described by music journalist Touré on his Twitter, was a mix of "'hood, prep, white, black, working class, trust fund rich."

Concertgoers got more than their money's worth: Jay-Z brought hip-hop's biggest stars with him on stage, including his wife Beyonce, Mary J. Blige, Kanye West, Diddy, Pharrell, Santigold, and Kid Cudi. One of the highlights of the night was when John Mayer joined Jay-Z on stage to jam along to "Me and My Girlfriend" and "D.O.A. (Death of Autotune)." Mayer also played a guitar solo of a medley of Jay-Z's most popular songs.

Beyonce drew squeals from the crowd when she performed a short yet high-energy version of her song "Diva" in a version of this spring's Sgt. Pepper-inspired Balmain jacket.

And Mary J. Blige, donning thigh high boots, jeans, a leather jacket and short blonde hair, joined Jay-Z on stage for "Can't Knock The Hustle."

Jay-Z paid homage to the fallen victims of Sept. 11 toward the end of the show. As his band played "Forever Young," a scrolling photo montage of the victims who perished on the day crawled behind the stage. "Make some noise for everybody who lost their lives so we can live ours," he called to the crowd.

Among the faces in the audience: New York Governor David Paterson, Katy Perry and Janelle Monae. And of the more sartorially adventurous: Amber Rose stood stage left in a one piece silver mylar jumpsuit, cut so low in the front that she was millimeters away from a wardrobe malfunction.


*For those that missed it live, Fuse will rebroadcast the concert exclusively and commercial-free on Sept. 15, 19 and 20."
