"I want to know the music that's in your head," Travers said. "I just want a snippet of what's going on in there."
Without an answer, Carell began singing Swift's song, "Shake It Off." Even better, the comedian kept a straight face the entire time.
"I love it. I actually love Taylor Swift," Carell admitted when his rendition was over. "I think she's great."
"Now, there's a confession," Travers replied. "That's the movie I want to see."
Swift is a big star, but that doesn't mean the compliment from Carell didn't completely blow her mind. The singer tweeted a response to the video, sounding like she may have been screaming like a giddy 12-year-old girl.

Meanwhile, Swift appears to be taking Carell's generosity and paying it forward. She has been sending personalized gifts to some of her very biggest fans.
