Kevin Hart is giving back to his close friend and personal trainer, who helped walk him after his 2019 car crash.

In an exclusive sneak peek at Monday's upcoming episode of Celebrity IOU, the 41-year-old comedian transforms the backhouse of his trainer Ron "Boss" Everline into a retreat as a "small token of my appreciation" for aiding Hart through intense physical rehab.

Hart expressed his gratitude to Boss for helping him regain mobility after the crash required him to undergo emergency back surgery.

"My life got flipped upside down by a tragic accident, and I had to kind of start over," the comedian said. "It's good when you have somebody to do it with you and walk you through it. And Boss was there with me every step of the way."

When it came down to demolition work, the comedian decided to "build the beef" with Boss' kitchen cabinets before taking a sledgehammer to it, as the opening clip above shows. The tactic got puzzled stares from hosts Drew and Jonathan Scott.

Hart, alongside the Property Brothers, decided to tear down the kitchen and rotted floors of Boss' backhouse to make room for a modern kitchen, a hidden bar, an open living area and a custom barber shop.

"This is a small token of my appreciation that Boss won't see coming and that will hopefully floor him," Hart said. "This renovation is well-deserved because of the person that he is."
