Jwoww showed off her body this weekend in Las Vegas -- and her new boyfriend!
Decked out in a tight black cutout mini-dress, the "Jersey Shore" star hosted a party at the MGM Grand's Studio 54, where she was joined with her new man, Roger Mathews.
Accessorized with feather earrings, a small clutch and some sexy stilettos, Jwoww also flashed her dragon tattoo the left side of her flat stomach.
While she and Roger were having a blast at the club, we're told she wasn't fist-pumping, and when asked about it she said "girls don't fist-pump.”
Situation, Pauly D, that's all you.
