But that night, they went glam, as Chyna sported a very revealing nude jumpsuit covered in black lace.
The reality stars danced to the music of DJ Big Ben along with some friends, documenting the fun on Snapchat. At one point, Chyna was surrounded by scantily clad dancers in pasties while she got an arm massage from a friend.
Rob, who rarely attends public events, seemed to be having a good time, wearing a black sweatshirt, sweatpants and a matching hat.
The proud parents welcomed daughter Dream two months ago and after fighting over the holidays, are back together once more.
Despite several recent club appearances, Chyna is still making time for both Dream and her son, King Cairo, whom she shares with ex Tyga.
