Their musical ride-along airs tomorrow on The Late Late Show With James Corden.
"She is amazing," Corden gushed about the "Perfect Illusion" singer at yesterday's Trolls premiere. "I love her. I got the pink hat and something happens in this carpool that's never ever happened before. We didn't think it was going to happen and it just did." (FYI: When I tweeted about Corden's tease, I received many replies suggesting that the thing that never happened until Gaga was that she got in the driver's seat.)
Corden was recently spotted in Los Angeles filming a Christmas-themed Carpool Karaoke with Mariah Carey. "I haven't seen it yet," he said. "I hope it's fun."
And then there's his Trolls co-star Justin Timberlake. Will Mr. SexyBack be making his Carpool debut in time for the movie's release on Nov. 4?
Corden cracked that he's already asked JT "a million" times to do it. His duets wish list includes "Señorita" and "Rock Your Body."
"One time I was at home and I went upstairs and I put the radio on and I was about to have the shower," Corden said. "I turn the radio on and the radio went, ‘I'm going to have you naked by the end of this song' [from 'Rock Your Body']—and he did. I was naked in the shower by the end of that song."
Perhaps it's time for some Shower Karaoke?
Corden said his five-year-old son Max loved Trolls but he won't be going as one of the colorful creatures for Halloween.
"He's going as Dory," he said. "It's going to be fun. He's obsessed."
