Rihanna is urging young girls not to embark on drastic diets in a bid to emulate catwalk models - insisting "size zero" is "not realistic and it's not healthy."
The 22-year-old star, who is famed for her slender figure and outlandish sense of style, is worried the fashion industry is indoctrinating women with an unhealthy attitude towards body image by only using super-skinny girls on the catwalk.
And the Umbrella hitmaker is adamant youngsters should never try to copy their idols because it is not "possible" to maintain such a tiny frame.
She tells Britain's You magazine, "You shouldn't be pressured into trying to be thin by the fashion industry, because they only want models that are like human mannequins. They know that if we see an outfit on a mannequin in a shop window we will love it and want to buy it whatever size we are. That's why they have size zero models - they want to sell clothes.
"You have to remember that it's not practical or possible for an everyday woman to look like that. Being size zero is a career in itself so we shouldn't try and be like them. It's not realistic and it's not healthy."
