CONOR McGREGOR is dreading his mum watching his X-rated opening scene as he makes his movie debut in Road House.
The UFC legend stars alongside Hollywood superstar Jake Gyllenhaal in the reboot of the 1989 Patrick Swayze classic.
And McGregor makes a notoriously grand splash on to the screen by baring his backside for all to see.
But the Irish icon, 35, admits his mum Margaret has no clue about the shock scene.
He said: "I have my mother coming in for the premiere tomorrow and she has no idea! I'm a bit nervous about it but excited.

"I just done my best. I had a great crew of people with me, a great cast and they were very patient with me."
McGregor plays the movie's antagonist, Knox, going up against Gyllenhaal's UFC star-turned bouncer main character.
And the former two-weight UFC champ shows off some of his trademark striking skills in the movie.
But his three sons Conor Jr, six, Rian, two, baby boy Mac and daughter Croia, five, will have a life-time ban on watching their daddy on the big screen.
The doting dad said: "Obviously, they can't watch and never will, to be honest. I'm nervous about my mother seeing it."

McGregor said: "He had a multitude of stunt guys and they got f***ed up, they actually got f***ed up and they wanted me to f*** them up.
"There was like spinning back kicks to the ribs and the director was like, 'No go again!'
