Ewan McGregor has jokingly called out Louis CK on his professed “man crush.”

During an appearance on cabler TBS' late night chat show Conan, host Conan O'Brien asked McGregor, who most recently played gay opposite Jim Carrey in the 2009 comedy I Love You Phillip Morris, for his reaction to comic Louis CK's recent declaration that he could go gay for McGregor.

O'Brien played a clip from a Louis CK comedy routine, in which he is seen saying, “The one guy I would blow, based on who he is, is Ewan McGregor. I'm not gay in any other way, except I want to fuck that guy right in the face … and I want him to fuck me.”

“I'd like to see if he would put his money where his mouth is, you know,” McGregor, 40, said with a big grin. “And I look forward to bumping into him!”

“Another way to raise money for charity,” O'Brien added. (The video is embedded in the right panel of this page. Visit our video library for more videos.)
