The man they call "The Notorious" has been all over the US media in the past few days and his interviews have been getting a lot of attention.
On Monday evening, he starred in a sports science documentary on FOX Sports and last night he was the main attraction on Dan Le Batard Is Highly Questionable on ESPN.
Le Batard's father was making a cameo appearance on the show and asked McGregor about his romantic side.
McGregor's answer left the presenters in stitches.
"I don’t know about romance but I like to get down occasionally," McGregor said.
"I don’t really have a romantic side is what I am saying. If I go for it, I’m going in for the kill, you best believe that.
"You will not catch me walking down the beach holding hands. You will catch me going deep."
