'Skinny' Blogger Calls Kate Upton Fat 'Piggie'

Kate Upton is known for her lush figure, but a blogger who acknowledges preferring the "skinny aesthetic" has likened the curvy swimsuit model to a cow and a pig.

In a June 10 post on the website "Skinny Gurl," the unnamed female blogger wrote: "Did you know that humans are 80% genetically identical to cows? Well, allow me to prove it to you… ." That line was followed by an unflattering photo of the back of Upton's lingerie-clad body on the runway.

The blogger wrote that Upton was "confidently lumbering up the runway like there's a buffet at the end of it," and also called her a "little piggie" with "huge thighs, NO waist, big fat floppy boobs, terrible body definition … ."

But the tables have been turned on the blogger. In a July 8 post, she wrote that she has been deluged with angry emails and threatened with rape and death.

The fashion world's most influential insiders have denounced the blogger and risen to Upton's defense.

"Running this site where you actually praise women for staying emaciated and skinny and then to go out there and then track someone who has a normal body, I mean, she's got issues," said Lesley Jane Seymour, editor-in-chief of MORE magazine.

"She's laughing all the way to the bank," supermodel and author Carol Alt said of Upton. "I would just say keep your end up and keep moving forward."

Online, the hacker group Anonymous launched a cyber attack against the Skinny Gurl website, forcing her to change web hosts.

It's all resulted in some changes to her site, among them the removal of the "Starving Tip of the Day" and the addition of language that "explicitly prohibits the glorification or promotion of self-harm."

She also wrote that she planned to add resources for help with depression, eating disorders, and self-injury.

Explaining the idea behind the site - which she says is "pro-skinny" but not "pro-ana" (for pro-anorexic) - she wrote: "As a thin person, I was also annoyed by our double-standards around weight. For example, people think nothing of telling a thin woman - to their face, in front of an entire group of people - how skinny they are and even to suggest what they should eat. But I've never seen the reverse happen to an overweight woman."

The blogger writes that she was a model in school and now works in the fashion industry.

"I take personal pride in keeping myself thin (since people keep asking: I'm about 5'7? and try to stay around 100 lbs)," she wrote. She adds that she stays anonymous because she has "a real-world profession with clients and partners and this is a controversial subject, even in places like NYC and Hollywood."

While she acknowledged that she has had her "own issues" with food and eating and that those issues had found their way into the writing on her blog, she noted: "There's nothing wrong with saying skinny is beautiful, just like there's nothing wrong with saying curvy is beautiful, or red hair is beautiful, or anything else someone happens to find appealing. It's an opinion, and we're all entitled to them."

For model Alt, the weighty war of words is another example of the extreme pressure the fashion industry places on girls.

"Sometimes in this business people's expectations are a bit unrealistic and it's very hard to attain those kind of expectations," she told ABC News.
