When Jenni "JWoww" Farley says "I do" to longtime boyfriend Roger Mathews, she won't be getting hitched down at the Jersey shore. Instead, the MTV reality star tells Us Weekly she has her sights set on a Sin City bash.

"I want to hit up every rockstar place in Las Vegas with my wedding party," JWoww, 26, told Us at Thursday's Jersey Shore final season premiere party at NYC's Bagatelle. In the meantime, however, the reality star -- who accepted Mathews' proposal while skydiving -- says she and her husband-to-be are simply "soaking in the engagement."

Having yet to transition into full wedding planning mode, JWoww has begun thinking about what her dress will look like. "I just want my boobs out," the busty star -- who showed off her 5-carat sparkler from Mathews at Thursday's bash -- hints. "I don't think I could hide them if I wanted to."

"I want 500 people at mine in Vegas and I'm sure she was 500-1,000. Small, simple," JWoww said of her pal and Snooki & JWoww costar.

When Snooki does walk down the aisle with LaValle, she'll sure look the part. "She already lost all the [baby] weight," revealed JWoww of Snooki, 24, who gave birth August 26. "She's phenomenal."
