Not everyone is celebrating Sports Illustrated's decision to put plus-size model Ashley Graham on one of its three swimsuit issue covers this year.

Former model Cheryl Tiegs, who herself has graced the cover of Sports Illustrated's swimsuit issue multiple times, criticized the magazine for what she sees as promoting an unhealthy lifestyle.

"I don't like that we're talking about full-figured women because it's glamorizing them because your waist should be smaller than 35 [inches]. That's what Dr. Oz said, and I'm sticking to it," Tiegs told E! News in a new interview. "No, I don't think it's healthy."

But Tiegs, 68, did compliment Graham's looks.

"Her face is beautiful. Beautiful," she commented. "But I don't think it's healthy in the long run."

When ET chatted with 28-year-old Graham earlier this month, the model could not have been happier with her gorgeous SI cover.

"I'm really excited to know that Sports Illustrated is wanting to include women like us," the size 14-16 model told ET exclusively. "There is no perfect body, and we shouldn't be striving for perfection anymore."

She has also talked about her health before, when ET spoke with the brunette beauty last August.

"The things that I don't necessarily like about it is all the negative stigmatisms that go with the word plus size -- you're fat, you're lazy, you have no drive, no determination, you're constantly eating," Graham told ET. "Honey, I work out. I work out three days a week. I lift. I do barre. I do it all. It's the stereotypes. That's what I really don't like. I am me. Take it or leave it."
