Matt Damon and wife Luciana, Jay-Z, Zac Efron and basketball player Baron Davis were all on hand for a performance from in-house entertainers the Hammerstein Beauties.
While Promised Land star Damon and his wife were "very lovey dovey," Efron spent his evening with a group of friends, an onlooker tells PEOPLE.
"Zac was getting a private show from the Hammerstein Beauties," the source adds.
Meanwhile, Jay-Z and Davis sat with advertising executive Steve Stoute.
But while Davis drank ginger ale all night and Stoute enjoyed a vodka cranberry, Jay-Z's drink of choice was water.
"They all seemed to be really interested in the show," the source adds.
