The party was crazy -- a bunch of the S.I. models turned up to turn up ... and when they displayed Camille's cover on the big wall, Rob and CK started dancing their faces off.
At one point, Gronk put CK on his back and began doing deep squats -- BECAUSE HE'S A BEAST AND HE'S ALWAYS LIFTING, BRO!!!
Before the club, a bunch of the models hit up Irma's at W South Beach for a kickoff party. Some of the stars in attendance include UFC's Paige VanZant, Tyra Banks, model Veronica Pome’e and Hailey Clauson.
