Clooney made mention of Fassbender baring all in Shame while accepting the 'Best Actor in a Drama' Award for The Descendants at the Golden Globes on Sunday (January 15).
"I would like to thank Michael Fassbender for taking over the frontal nude responsibly that I had," Clooney said jokingly of fellow nominee Fassbender.
Fassbender was asked about Clooney's joke after the Golden Globes wrapped up last night.
"I love him, man," Fassbender beamed to Access Hollywood.
Clooney also teased friend Brad Pitt at the Golden Globes during his introduction of a clip from the film Moneyball.
The Descendants star revealed that he'd stolen the cane Pitt has been using for the past few weeks since injuring himself while carrying his daughter Vivienne.
"I have to give it back to him. He can't make it to the bar otherwise," Clooney joked.
Clooney's win on Sunday for The Descendants gave the star his third Golden Globe Award.
