The reality tv starlet was spotted snacking on Sugar Factory sweets at Paris Las Vegas with her fiancé Roger Mathews.
The lovebirds playfully fed each other red and black licorice piece, energy filled gummy bears and Swedish Fish.
But the sweetest thing was the huge rock that JWoww showed off while noshing on her favorite sour gummy worms throughout the night.
JWoww and Roger were dressed up as sexy nerds for the festive occasion and looked adorable.
Happy Halloween Everyone!
