Rodriguez/WireImage Cheryl Tiegs is not okay with Sports Illustrated‘s new cover star, the size-16 Ashley Graham. “I don’t think it’s healthy,” the former SI Swimsuit Issue star told E! News. “Her face is beautiful, beautiful. But I don’t think it’s healthy in the long run.” Tiegs believes the rise of full-figured models is problematic because of the message it sends. “I don’t like it that we’re talking about full-figured women because we’re glamorizing them, and your waist should be smaller than 35 [inches]. That’s what Dr. Oz said and I’m sticking to it.” Graham made history Feb. 13 when she was named the first size-16 model to land the cover of SI, along with UFC fighter Ronda Rousey and two-time SI model Hailey Clauson. “I thought Sports Illustrated was taking a risk by putting a girl my size in the pages,” Graham told PEOPLE after her cover reveal. “But putting me on the cover? They aren’t just breaking barriers; they are the standard now. This is beyond epic.” And Twitter mostly reacted in kind, giving Graham and the magazine props for her groundbreaking cover. Tiegs was a fan of Clauson’s SI spread, and posted one of her photos on Facebook with the caption, “I remember posting a picture of a beautiful swimsuit model on my refrigerator. It gave me the inspiration to have a thin, #healthy, strong body. #HaileyClauson #Motivation”
