We have another hot topic burning up the "gma heat index." Kelly cutrone was speaking out about ultrathin models, giving her take on the real reason they're so popular. Abc's linsey davis has the story. Reporter: The fashion industry is constantly under fire for sending models that appear to be stick figures down the runway. Very condescending and rude. Reporter: Now, one of fashion's major insiders is speaking out. The no nonsense publisher and judge of "america's next top model" kelly cutrone, says society needs to blame itself. We like to think of ourselves as a modern society, america. But we have very narrow-minded beliefs about what is beautiful. My take on it is that american women want to see thin models. If the public thought that 400-pound purple people were attractive, fashion people would be the first person there to make the garment. Reporter: When they saw the real women campaign, they saw the sales go up. It was a shock. Having a real woman campaign was saying, like, we're doing green people for halloween. People were checking it out and talking about it. Reporter: Some of the big campaigns in the fashion industry appear to be expanding their lines along with the waistlines. H&m has a plus-size model for one of its ad campaigns pep and high-end designers, like michael kors and calvin klein are making plus-sized pieces for their lines. Do you think the fashion industry is starting to embrace the larger size woman now? I think they will throw a bone to the media. I think the fashion industry is behind. There's not enough diversity in ethnicity in models, anywhere in america. Reporter: If the public thinks her words seem a little too cutting -- I think you need to put some gratitude in your attitude, girl. Reporter: The fashion phenom says she's not sorry for calling the cat catwalk the way she sees it. Am I stutough because I say that? Am I going to tell the truth? Yes. Is it my opinion? Yes. Reporter: For "good morning america," linsey davis, abc news, new york.
