British comedian Russell Brand says his lack of confidence to dance in public makes him rehearse his moves secretly.

He admits he lacks confidence in his ability to move to music, insisting he isn't very graceful, reports femalefirst.co.uk.

'I always do that because I have to practice it for when I'm doing it in my films, I look at myself thinking, Oh God. Is this what you're really gonna expose to the world? Just to see if I can cope with it at first,' he said.
