Shawn Mendes is featured on Camilo's official remix to "KESI." But it wouldn't have been possible without some help from girlfriend Camila Cabello. She was a little tough on him about it though, according to him. He said:
"She was like, 'If you're going to do this, you got to do it right. You can't be saying these words wrong.' And I was like, 'Okay.' It took me hours to get the words right -- I could not mess that up. It was going to ruin our relationship... I remember there was one word and I was like, 'I think it's fine.' And she's like, 'It's not fine.' And I'm like, 'Okay, it's not fine. I believe you.'"
