Supermodel Naomi Campbell is blaming her infamous violent outbursts on cocaine abuse.

"You become short-tempered. You know," the New York Post quoted her as saying.

"Your little charm goes. The little glow in your face goes. It's a very nasty drug. I think what is very scary about cocaine is that you start to feel too confident and you start to feel indispensable, although none of us are indispensable."
