Not everyone is on board with plus-size model Ashley Graham's Sports Illustrated Swimsuit Edition cover.

Former multiple-time cover model Cheryl Tiegs recently revealed her feelings about Graham gracing the cover along with Ronda Rousey and Hailey Clauson for the 2016 edition. Tiegs said she didn't think Graham's appearance in the magazine was a good thing because it is "unhealthy" to be her size

"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]," Tiegs told E! News.

Graham has had to overcome a lot of diversity in her modeling career, but likely won't let Tiegs' negative comments bring her down.

"The moment I realized I had to be healthy and happy in who I was, that's when my career took off."

It's unlikely Tiegs' criticisms will take away from the elation Graham felt at being included in the magazine:
