Bradley Cooper was nominated for an Oscar for his much-talked about performance as Chris Kyle in "American Sniper." But there's one thing people just can't stop talking about in the movie -- the fake baby used as a prop.
Cooper visited "The Ellen Show" on Monday and discussed the fake baby gaffe with the host.
"I literally, I couldn't believe it," said Cooper, who wiggled the fake baby's arm at one point during a scene to make it look more real. "I couldn't believe that we were working with the plastic baby. I was just like, 'This is nuts.'"
In between laughs, Cooper continued, "Eat your heart out, 'Muppets."
Watch Cooper talk about the experience more in the clip:
Sienna Miller, Cooper's co-star in the movie, was on "Ellen" last week and also talked about the fake baby.
"It looked like something from 'Alien,'" said Miller.
Correction: A previous version of this post said that Bradley Cooper played Chris Kelly in "American Sniper." He played Chris Kyle.
