Rob “Gronk” Gronkowskimay be retired from the game, but the former New England Patriots star is keeping himself fit with a little help from his girlfriendCamille Kostek!
Thursday night, Gronkowski, 29, and Kostek, 27, put their love on full display at the model’s star-studded party, celebrating her 2019Sports IllustratedSwimsuit coverat Irma’s and Wall nightclub at the W South Beach Miami.
At one point in the night, Gronkowski got behind the DJ booth and put Kostek on his back and began doing serious squats as his lady love held on tightly.
Kostek flashed a nervous smile as Gronkowski nearly went below the booth while doing the exercise. She later loosened up and was recorded pretending to whip around a lasso as Gronkowski danced wildly.
Kostek shared the hilarious moments on her Instagram Story.
When he wasn’t working out with Kostek, Gronkowski decided to be her personal bodyguard. Gronk was standing at the VIP section ofSI Swimsuitmodel’s roped-off area at WALL, acting as a gatekeeper to make sure all those who tried to gain entry belonged with his new cover girl’s crew, a fellow partygoer tells PEOPLE.

Gronkowski and Kostek were first romantically linked in 2015.
Last week, Gronkowski — whoannounced his retirementfrom the NFL in March — joked about how he may still “convince himself” to return to the sport.
However, Kostek says Patriots fans shouldn’t get too excited — “he is someone who likes to mess around,” she said in aninterview withExtra.

“I think he is messing with everybody, then again he stumps me all the time so who knows?” theSIcover girl said. “He could be pulling this out of the woodwork at some time. I would love to see him out there, but I am also respecting him taking this time for himself, healing up his body, and enjoying the time off.”
Kostek is a former Patriots cheerleader, which was one of her first ties to the former athlete.
“It’s been a blast,” Kostek toldExtra. “I was cheerleading on the sidelines in the first couple years … I went from cheering him on the sidelines of the Super Bowl to being a proud girlfriend in the crowd to [watching him end] his career on the Super Bowl field … I feel very lucky that I got to be a part his incredible career.”
