Newishweds Mariah Carey and Nick Cannon played host at Marquee nightclub in NYC last night at the club’s annual Halloween party. Nick actually did double duty as he also DJed last night’s soiree … Mimi, on the other hand, was just there to look hot. Here are a couple pics of Mr. & Mrs. Cannon making their grand arrival at Marquee last night in their matching firemen costumes:

Mimi and Nick arrived on the back of an actual NYC firetruck to much fanfare … but the couple did not remain in these costumes for long. Once inside, they both changed into other matching (and IMHO, cuter) Halloween costumes. After the jump, check out pics of Mimi and Nick‘s second Halloween costumes of the night …

OMG, I love it! Milk & Cookies! Brills. They look great in these costumes. I understand that Nick‘s milk carton costume came equipped with a spout/nozzle that dispensed milk from his crotch region … which is wholly gross but I suppose apropos. Mariah looks so cute as “cookies”. I’m not usually a fan of matching couple costumes but, I gotta say, I like these costumes very much. They’re cute, right?
