Kate Upton is on dual covers of V magazine's spring preview issue where she discusses her good looks and speaks on harsh words she once received.

"I don't compare myself with other models," the 21-year-old told the magazine. "For me, modeling is really about competing with yourself, becoming the best you can be."

However, the star admitted that there's certain poses she can't pull off the same way other models in the industry do.

"The truth is that I can't do facial expressions like [Coco Rocha] and others do. If I pull a goofy face, it doesn't look cute; I look like a dying animal," she said. "But I guess someone likes what I am doing."

Yet, despite her massive success, Upton hasn't always received praise from industry moguls. When she was 19 years old, Upton was dissed by the casting director of Victoria's Secret shows.

"She's like a Page 3 girl," Sophia Neophitou told The New York Times in an interview in 2012. "She's like a footballer's wife, with too-blond hair and that kind of face that anyone with enough money can go out and buy."

The blonde bombshell spoke about the incident with V and explained that it was good preparation for the life she would soon need to get used to.

"You have to remember that I was 19 when she said that, and I had just gotten my cover of Sports Illustrated that day. Literally that day. So it didn't really affect me at first," the model said. "But it did in the end, because I wasn't used to that kind of media swirl at all. I had never met her, so it really came out of nowhere. It was my introduction to being in the spotlight and having people you've never met have an opinion of you."
