Carey not a fan of size zero

American singer Mariah Carey has blasted the size zero craze and is urging women to "embrace" their natural physiques.

The voluptuous singer, who unveiled a new look at VH1's Save the Music gala in New York on Thursday, admits to living on a "bleak diet" to maintain her figure.

But Carey, 37, vows never to starve herself to become a "stick figure girl".

"My secret is bleak diets, I still feel like I have a way to go," she said.

"I don't feel like you have to be a size zero. We should all just embrace who we are physically.

"I'm not supposed to be a stick figure girl. It's just not me."
