Shawn Mendes

It's hard for me to just say, 'Wow, this is amazing - I'm famous. I'm living the dream.' I sit there and think, 'I'm scared - this can go away tomorrow.' My dad always says that I'm a tortured soul because I'm never pleased; I never feel like I deserve what I've achieved.

John Mayer would be my ultimate collaboration because he's just the man. He has basically captured all I believe in with music.
