Nicole Snooki Polizzi attend the Sin City Halloween party at a spine-chilling Halloween bash in Las Vegas, Nevada on Saturday night (October 29). The "Jersey Shore" star joined a gal pal with the two ladies decked out in feline costumes as they made their way to the VIP area at PURE Nightclub at Caesars Palace.

Sending out countless tweets before, during and after the Sin City soiree, Snooki kicked the messaging off by writing, "I take halloweiner very seriously. Rawrrrrr" Nicole Snooki Polizzi At Sin City Halloween

As she arrived to the popular nightclub, Miss Snooki worked the arrivals carpet before visiting the deejay booth and grabbing drinks with her pal as she tweeted, "At my fav club pure with @kgillean @salwise783 my loves! Xoxoxooxo"
