Bar Refaeli gets upset when she sees painfully-thin models.

The Israeli supermodel - whose curvy-yet-toned body is the envy of women all over the world - hates seeing young girls look so unhealthy and wants them to be encouraged to put on some weight.

“I get so sad when I see 15-year-old pale extremely skinny models at the agency looking all shaky and hungry. when will it end?!?!? (sic)” she posted on her Twitter.

She has also hit out at women who have plastic surgery, saying they are setting a bad example to young girls: “Seriously. plastic surgery is not helping your impact on young women or your looks.”

Despite being voted one of the world’s most desirable women, Bar recently revealed she feels at her sexiest when dressed in simple clothes. “It’s mainly about how you feel. I wouldn’t feel sexy if I was walking around in high heels, a tight top, huge earrings and an elaborate hairdo all day. But there are women who seem confident and sexy like that. It’s a lot about how you move in your outfit and if you feel comfortable in it. I like comfortable clothes - long dresses, jeans, shorts. I like it simple and prefer not having to accessorise a lot.”
