NEW YORK CITY // THURSDAY, OCTOBER 30TH 2008 » You thought you were the only one who dressed up for Halloween this year? Newlyweds (are we still allowed to call them that? lol) Mariah Carey & Nick Cannon dressed up as firefighters and threw a Halloween costume party at club Marquee in New York Thursday night. But you know the Cannons didn’t just leave it at that. The two changed costumes once they get inside the party. Peep what they wore after the break!
