“You see I have a waist right here? I don’t have one in real life anymore… but what they do is they move your organs around… There was a metal corset and it [took] two Italian people… And the next thing you know, my ribs were compressed… These people move your ribs, and they move your liver out of the side and they pop you in,” Jennifer said.

“You step into a bodysuit first… like a leotard, but it’s a thong. So I was in that, and we were watching the Academy Awards… and suddenly my ribs started to panic. Everything in here started to freak out,” she continued.
