America's Next Top Model Cycle 20 and its participants apparently experienced more tension and stress in real life than what viewers are shown on the hit television show.

For one, the photo-shoots look quick on the show but the models were actually shooting and working all day. 

Don, one of the male models on America's Next Top Model Cycle 20, said, "Oh my God, we were there for like 13 hours at least every day."

Mike, another male model on Tyra Banks' hit television franchise America's Next Top Model commented, "We'd get up at five in the morning, get home at midnight. They make it seem like it was so quick, but really it was just all of us hanging around all day."

Viewers see the models most tense during panel. Apparently, it was even worse on set of America's Next Top Model Cycle 20.

"We're up there all day," Don, who suffered two panic attacks on the show, told entertainment reporters. "It's freezing in there. Your legs are shaking, because you're like, Did I do good? Panel is very stressful." 

Being cut off from the real world added to the tension.

"We had maybe five minute phone call time a week, so it was really hard to not be able to talk to nobody, to know what was going on in the regular world," Don goes on revealing. "There was no news." No TV. No internet. No iPhones. Just the pleasure of each other's company. "

America's Next Top Model is a reality television show that started airing in 2003. It originally was shown on the channel UPN until UPN merged with The WB and created the network The CW in 2006. The show was conceptualized by supermodel Tyra Banks. Banks also acts as an executive producer and host on the show.

America's Next Top Model Cycle 20 is the latest season of the show.
