On the red carpet at the 2017 American Music Awards, Mendes talked to Billboard about what it’s like performing with the singer.
“He’s the coolest person in the world, first of all,” Mendes says of Mayer. “He was so calm and I was freaking out and he was like, ‘It’s going to be fine.'”
When asked about whether or not they’d work together more in the future, Mendes said that the pair do talk a lot. “We’ve become really good friends. I kind of consider him a mentor of mine…but I think so. We’re never in the same place at the same time but I think we will.”
