"They called it the couch," Chrissy told ET's Brooke Anderson. "It's basically couch cushions ...We had a separate dressing tent, because I couldn't go in and out of my trailer," Chrissy added, revealing that she actually got stuck in her trailer because of her fat suit.

Set in the 1950s, AHS doesn't shy away from the cruelty and prejudice that an obese person would have encountered in that era.

"I don't believe that people are overweight because they choose to be overweight, as controversial as that might sound," Chrissy said. "There's a lot of other things that are going on, but in 1952 anybody that was remotely different -- not even as attractive as the next door neighbor -- you're getting labeled."

Unfortunately, even in 2015, there are still those who exhibit hateful speech towards people that are overweight.

"I remember my sister calling me. She was like, 'Chrissy, there's some mean people saying mean things about you,'" Chrissy said. "I was like, 'They don't know me.'"

Chrissy is able to shake off the critics and even shared a love scene with Emma Roberts' fiancé Evan Peters on the show. She admitted to ET that the shoot was awkward considering she had to do it in front of Emma, who also co-stars on the FX series.

"It was awkward, and I thought, 'Chrissy, this is a job. You didn't write the show. You're here to do a job.' And Emma was fine."

After being on the show, Chrissy has become a role model for girls. She told Brooke that she's gotten messages from fans calling her an inspiration to them.

The season finale of American Horror Story: Freak Show airs tonight at 10 p.m. ET/PT on FX.
