Diddy is taking his act to Jersey — for a hefty 75G. After no New York club would meet his extravagant demands to host an after-party for his “Dirty Diddy Money” show Friday, the rapper signed with Club 4 Sixty 6 in West Orange this week, sources said. The deal, made with promoter Vegas Style Entertainment, gets Diddy $75,000 plus a private helicopter ride across the Hudson. He’ll also have use of a new Bentley Continental GT in the Garden State. Diddy’s demands had New York club owners up in arms. “After the cost was revealed, we were not in the running,” said one. “We were running away.” Diddy’s rep didn’t get back to us.
