Back of Nick Lights Mariah's Fire While She Sweetens Him Up New York's finest, Nick Cannon and Mariah Carey, hosted a Halloween Eve Costume party at Marquee last night and had fun posing with a wardrobe change in the middle. The couple showed up to the party on a FDNY firetruck and then once inside changed into their milk and cookie outfits. Considering how Mariah dresses day-to-day, it's no surprise that she went super sexy for the holiday, but at least that one is a little more original. We know these two love being photographed and while it's fun to see their costumes we can't wait to see who else will be out celebrating Halloween.

I love it! HeatherStJoeMI 8 years I like the Milk & Cookies. youcrazymofo18 8 years Yeah, I would say she should stop dressing like a teenager, but I'm a teenager and I would never wear any of that! californiagirlx7 8 years Call me crazy but I like their milk and cookies costumes. Very creative ensembles. The firefighter outfits are trashy though. This couple is just odd... CherryPop- 8 years blah tuscanstellina 8 years Maybe when she gains some intellect, she will obtain some class as well. lem0n_ 8 years the firefighter outfit is really distasteful, i can't believe someone would wear that... aras8218 8 years thay look like they have fun together Manoukia 8 years So she went as a firewh*re, or what? Penny4545 8 years her famous amos cookie costume was cute. He's just goofy in the milk one. But at least they're having fun. She deserves it. He's just a REALLY lucky guy. FoxyJo 8 years aww milk and cookies...cute idea! nourhayaty 8 years i like the cookie and milk costume but the firefighter's costume is not so much LOVE-ANGELINA 8 years I like them and I think first costume is soooo cute. sandy82 8 years the cookies and milk costumes are really cute. very original. mariah's fireman costume looks nasty. It's insulting to the FDNY. With the fireman's hat she's wearing.. it just seems distasteful. mushaboom 8 years Gross. I really wish she would wear more clothes. Lavinie 8 years omg! she is making me want to start a campaign - for her to stop wearing such skanky looking clothes.. . she is not 20! if anythign - she's almost 2x that age.. and nick just looks dorky.. ugh. ckeller825 8 years LOL, I can't believe she married him. He looks like a younger brother rather than her husband! They just look soooo odd together. PinkNC 8 years Why must she always dress like a street walker. No matter what she has on, her ass and tits are shown to the world. Amethyst 8 years This is no different than how Mariah dresses every day. I was hoping once she got married, she'd get some class in her outfits like Jennifer Lopez did. Guess not. She still dresses like a floozy. bluestar 8 years barf spicyaroma 8 years I like the first costume. But the firefighters one is just trashy. UrbanBohemian 8 years Honestly, I think the milk-and-cookies pair costume is cute. outofhere 8 years Yuck. sham28 8 years And cari, cute avatar, I like happy pretty Lindsay pictures, and I think she's going to make a Mean Girls- caliber comback, screw the haters. :) sham28 8 years She's always dressed inappropriately young- in interviews she's mentioned that she's like a 12 year old girl in spirit, which might also contribute to her obsession with butterflies and hello kitty. It's a little bit creepy actually. But obviously, there are few voices like hers in the universe. It would be cool if that wacktastic marriage worked out.
