NYC's craZZZiest nightclub owner, Simon Hammerstein, invited half of Hollywood to come celebrate the grand opening of his new Las Vegas creation… ACT!
We hear Act is MUCH more tame than Hammerstein's first famous club, Box, which is known for its VERY naughty performances (i.e. women lip-syncying songs… NOT with the lips on their faces).
BUT what it lacks in va-jay-jay-singers, they made up for in celebs!
See pics of the party popp'n stars (below)!
