Flirtatious Jersey Shore star Jenni 'J-Woww' Farley kicked off Halloween weekend last night at Chateau Nightclub & Gardens at Paris Las Vegas seductively dressed as a gangster.

Joined by boyfriend, Roger Mathews, UFC Lightweight World Champion, Frank Edgar and wife Renee, the buxom brunette walked the nightclub's red carpet before heading inside. Complete with toy "gats" and feathered hats, the crew made their way to a VIP booth overlooking the packed dance floor. Enjoying Grey Goose and soda, JWoww danced and high-fived fans from her table.

Later in the evening the Jersey girl took over the club's microphone to thank the crowd for coming. The gangster group then headed upstairs to Las Vegas' newest hot-spot, Butterfly at Chateau Gardens. Settling in for the night, JWoww took in the extraordinary views of the holiday inspired rooftop party-spot. Alongside elaborately clad characters dancing on platforms under the Eiffel Tower, the Jersey star party rocked the night away above the famous Las Vegas Strip.

The new Chateau Gardens is situated on the rooftop of Paris Las Vegas under the awning of the Eiffel Tower. Reminiscent of a lush garden in Versailles, Chateau Gardens spans 22,000 square feet in an unparalleled setting beneath the stars. Butterfly, held every Saturday night at Chateau Gardens, is an ultra-sensory nightlife experience that combines the talents of the world's top DJs, producers, singers and performance artists.
