This is what it's like when celebrities go hard.
Jimmy Fallon and Justin Timberlake continued their epic night in NYC on Wednesday along with a cavalcade of celebrities, including Jennifer Lopez, Casper Smart, and Kate Hudson, who wore a SUPER low-cut jumpsuit that appeared to land the actress in a close call with a wardrobe malfunction.
An eyewitness tells ET that after Justin's Tonight Show return, followed by his show-stealing U.S. Open appearance with Jimmy, the two were joined by J.Lo, Casper, Nick and Kate at the 40/40 club, before the group -- sans Jimmy -- moved on to the Game nightclub.
Justin partied on at Game until after 4 a.m.! We're told his drink of choice was Tequila.
"Everyone was so happy," the eyewitness reveals. "Casper had a talk with his old driver who now drives Timberlake. Jimmy is always all smiles."
Earlier in the night, J.Lo, Casper, and Kate stopped off at Nick's concert, where Hilary Duff, Hailee Steinfeld, Gigi Hadid, and Joe Jonas were also in attendance.
