Sam Smith has called preparing for the Grammy Awards an "un-human experience".

He's performing at America's biggest music awards show in Los Angeles on Sunday night, where he's up for six prizes.

Sam said: "I just feel very overwhelmed and I'm just trying to concentrate on not to trip on stage - not that I'm doing much dancing!"
