UFC heavyweight champion Francis Ngannou stars in the Jackass movie, where he punches an opponent in the GROIN.
The 35-year old took some time to create some funny content with the famedly absurd comedy group.
Ngannou is currently the UFC heavyweight champion
Jackass Forever is coming to UK cinemas February 4, and Ngannou was given the task of punching one member of crew in the groin.
After shooting the clip, he revealed that Jackass guys had told him to use more force after the first take.
The UFC star spoke out about his role in the film, saying that it was "the craziest thing I've ever seen."
"Man, I had no choice but to punch someone in the nuts. It was the first time I tried it. You're known as the best puncher in the entire world. It was not easy.
"I was like, 'Are they kidding me?' I mean, I'm nervous.
"I don’t know, I could harm this guy, did his at least have children or something?"
Ngannou, the Jackass member at the end of the punch, gave the Jackass member a real shock when he walked around the corner at start of scene.
It was because Johnny Knoxville, Jackass leader, lied to him and said he would be punched by a lightweight.
Ngannou is widely regarded as one of the most hard-hitting fighters in UFC history.
The French-Cameroonian is currently preparing for his defense against Ciryl Gane at UFC 270, January 23.
He has made headlines recently for a different reason, however, after calling out Tyson Fury, boxing's heavyweight champion.
He believes that it's only a matter time before he swaps out the octagon with the squared circle, and has named Fury as potential opponents.
Ngannou stated to TMZ that it's been always down the line. This is something that I won't let go of.

"Tyson Fury Deontay Wilder. That would be a great goal. This is not the same sport. Although I am the champion, it's not the same thing.
"At the end it's about trained hands, trained punches and having a good delivery method to produce bombs. I'm confident that if my punch is good enough, I can do some damage."
