Lil Jon led Monday night’s exceptionally animated Halloween bash at Surrender Nightclub at Encore Las Vegas. The night included a “Best Costume” contest with a $25,000 cash and prizes giveaway.

Alter egos were out in full force as Halloween revelers and Surrender staffers dressed in an imaginative array of costumes that ranged from the bizarre and frightening to the traditional and naughty. Pumping up the capacity crowd in his high-energy manner, Lil Jon kept party-goers on their feet moving to his signature sound.

The $10,000 grand prize went to a group from Ohio, who dressed as Transformers.
