According to the New York Post's Page Six, Kate Upton was photographed in space to celebrate the 50th anniversary of Sports Illustrated. The 21-year-old model didn't actually travel to space but was shot in a silver swimsuit in a zero-gravity chamber "with weightless ample bosom and big hair that made her look like something out of 'Barbarella,'" the source told Page Six.

Upton is no stranger to posing in sexy shoots for the magazine; she's landed on the cover of Sports Illustrated Swimsuit Editions in 2012 and 2013.

According to the source, the magazine also photographed a number of legends in the industry like Tyra Banks, Christie Brinkley, Bar Refaeli and Carol Alt.

The cover girl for the 2014 issue has not yet been decided. Besides posing for Sports Illustrated, the model also did a shoot for V magazine to go along with her cover story, E! News reports. She talked about a number of things including not viewing other models as competition and how she is able to work the camera so well.

"I now suffer from Catalog Tourette's," Upton joked to the magazine. "I can switch a pose like it's no one's business. As soon as I hear a camera click, I'm on. I tell you, it's a serious nervous condition."

Even with all her success Upton said she refuses to let the fame and attention go to her head. So how does she manage to stay so grounded?  

"I don't compare myself with other models," she said. "For me, modeling is really about competing with yourself, becoming the best you can be. 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. But I guess someone likes what I am doing."

Upton does have a lot of admirers but last year Victoria' Secret Fashion Show director Sophia Neophitou slammed the model during an interview with The New York Times.  

Neophitou said that Upton "was like a footballer's wife, with the too-blond hair and the kind of face anyone with enough money can go out and buy."

Upton told V that she was really confused by the comments because she has never met Neophitou before.

"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," she said. "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."
