Police in Atlantic City shut down the party early Monday and forced about 1,800 guests out of the Harrah's Resort nightclub known as The Pool.
Authorities say the trouble began after midnight when an estimated 500 people in line tried to force their way in. All the casino's bars were also closed early because of the brouhaha.
One man was arrested and charged with obstructing the administration of law and resisting arrest, but no injuries were reported.
Several celebrities had been scheduled to appear, including boxer Floyd Mayweather.
