Reality TV stars Scott Disick and Jonathan Cheban had quite the boys' night out Wednesday.
First, the gents cruised Gotham in Scott's Maybach, going shopping and hitting up the hot spots before the sun went down.
Celebrity wedding guru Colin Cowie and Niche Media Holdings founder Jason Binn threw the gala bash, which also drew stars like N'Sync singer Lance Bass; Real Housewives Ramona Singer and Alex McCord; LaLa Anthony; and socialite Tinsley Mortimer.
Disick and Cheban then headed over to the after-hours party at Hell's Kitchen restaurant Southern Hospitality, where A-list owner Justin Timberlake was in the house for an impromptu performance.
Disick and Cheban played it cool, nursing drinks and puffing cigars in the star-soaked atmosphere.
An insider at the bash called it “a real young Hollywood event" as stars like Emma Roberts, Emma Watson, Amanda Seyfried were all there, drawing major attention in a New York minute.
"Cops were everywhere there was a huge crowd gathered on the street,” the insider said.
