Kate Winslet, whose "decadent flesh" has been admired by fat-free fellow thespian Keira Knightley, is fed up with the undernourished ideal so popular among today's starlets.

"This skinny thing, it angers me so much. It disturbs me," the amiable actress fumes to OK! magazine. "I don't understand the fascination with it. The interest in certain people, like Nicole Richie, in regards to weight, is incredible, and it's a mystery to me."

Winslet, 30, who these days is sporting a lithe but still fabulously curvy figure, says she's "flattered" that some might consider her a role model, adding that it's not a responsibility she takes lightly.

"Now, more than ever, I feel this tremendous sense of staying the same shape and saying 'Look! I get pimples, too,'" she explains. "I really do, by the way."

According to Kate, weight is not something she discusses with husband Sam Mendes and kids Mia, 6, and Joe, 2, nor is it something she worries about when it comes to squeezing her once overly scrutinized body into the latest fashion trends.

"I'm happy with my shape and size," she declares. "I accepted a long time ago that I wasn't going to be able to wear skinny jeans. I'm fine with that. In the past, people have been a little unkind when it comes to discussing my weight, but I realize it's them, not me. I'm totally fine with how I look and the weight I am."

Also weighing in (groan) on Hollywood's body image obsession is Winslet's "Sense and Sensibility" costar Emma Thompson, who kvetches (via the London Daily Mail) of appearing on the big screen, "It's such a burden having to look good."

The two-time Oscar winner, 47, thinks she'd fit in better in French cinema, because "women are allowed to have really big bags under their eyes like mine and they're allowed to be older and still be female and beautiful and sexy and everything."

That's not the case in the U.S., says Thompson, where "everybody wants you to be twelve and size zero and it's like, no, I don't like it."

Neither does Petra Nemcova, who admits she resorted to unhealthy and uncomfortable lengths to become a human coat hanger.

"I went through so many diets in my life. I've been very, very skinny. I've been a size zero but I'm naturally more curvy," the tsunami-surviving supermodel tells People. "I ate just vegetables, carrots, tomatoes. I went from a just-protein diet to just eating apples to eating no carbs. I took laxatives. I went through all of it just to be able to model."

And speaking of size zeros, if the wincingly wasted sternum Kate Bosworth inadvertently flashed during Fashion Week a few days back had you racing for the Ho-Hos, you're not alone.

The New York Daily News has now labeled the already attenuated actress, who recently called it quits -- again -- with Orlando Bloom, "superskinny."

"She looks scary," a mole who spotted Bosworth at an NYC restaurant tells the paper. "At first, I wasn't sure it was her, because she was so tiny."

Alas, there's no word on whether Kate managed to down some calorie-crammed sustenance at the eatery, but at least she can take comfort in knowing that Giorgio Armani has her bony back covered.

"Ever since I started out as a fashion designer, I chose to use models who were on the slender side," he writes in the London Independent. "This was because the clothes I design and the sort of fabrics I use need to hang correctly on the body."

Armani, however, brushes off any responsibility for the cadaverous catwalker trend, explaining, "As so often in the fashion world, things have been taken to extremes. And unfortunately there are a lot of young women who never accept that they are thin enough -- and this is an illness."
