JAY-Z AND FRIENDS: Jay-Z, Vanessa Williams, Kelsey Grammer and Nick Cannon were among the celebrities at Audemars Piguet’s auction of 12 watches on Monday night to raise money for Broadway Cares Equity Fights AIDS. Before auctioning his personalized Audemars Piguet watch, Jay-Z said, “Hi, everyone, I kind of don’t want to part with this. So I hope it goes [for a small amount] so I can bid on it.” Jay-Z lost that battle, however, handing over the timepiece for $220,000. Williams, who is appearing in “Sondheim on Sondheim,” presented her signed Lady Jules Audemars model for auction. Audemars Piguet chief executive officer Francois-Henry Bennahmias made sure to encourage the bidding. The auction at the Four Seasons hotel raised $816,000.
