Sam Smith was so worried and "scared" of performing on Saturday Night Live that he begged not to appear.
The singer credits his American success to appearing on the popular show back in March, but admits it was initially something he thought as a bad idea as he was completely unknown at the time.
Speaking to Billboard magazine he explained: "'Saturday Night Live' is the thing that broke me in America, but I was very scared, and I actually begged my team and my label to not do it when we got the call.
"I thought it would have more impact if I had a song out and on the radio."
Fortunately for Sam his team insisted he performed and he went on to enjoy overnight success in the States.
He added: "But I was so wrong. I had a story all of a sudden, and I was on people's iPods in the space of a week."
Sam's success has been further cemented this month as he picked up six Grammy Awards, including Best Album for his debut LP 'In The Lonely Hour'.
"I'm just excited to go there because last year I was there and I sat in the very back and no one knew who I was!"
