JWoww, Fiance Roger Mathews Geek Out at Halloween Bash in Las Vegas (PHOTOS)

'Shore' stars congratulate JWOWW on her engagement.
Jenni “JWoww” Farley and her fiance, Roger Mathews, got in touch with their inner-geek Saturday night when they showed up to a Las Vegas Halloween party as matching nerds.

Dressed in suspenders, bow-ties and taped-up glasses, the future man and wife truly got into character at the event — especially JWoww, who was photographed crossing her eyes and sticking her tongue out on the red carpet.

The event was held at the Chateau Nightclub & Gardens at the the Paris Las Vegas.

Last week, Celebuzz spoke to JWoww — who got engaged to Mathews in September — during which she admitted she hasn’t even started planning her wedding yet.

“I’d like to say next year, around summertime,” the 26-year-old Jersey Shorestar said. “But every time I keep looking into that, I’m hearing like, ‘You have to plan, like, a year in advance for a venue and blah, blah, blah, and it takes this month for this invitation’ … And I’m like, ‘Oh my God … My goal is next summer, but I haven’t even picked the venue yet. [Laughs]”

She also admitted she isn’t worried about squeezing into her wedding dress.

“My big thing from here until whenever my wedding day is just to live healthy — exercise 30 minutes a day, [do] some cardio, weight training, substitute some of my carbs that I love for some natural carbs like vegetables, take your supplements,” she said. “Just live your life so on your wedding day you feel healthy and you’re not starving in your wedding dress and ready to wolf down the whole cake.”
