After seven women painted Jennifer's naked body - in blue - for several months, the diva lost her self-conscious. Lawrence had to endure that because she plays mutant Mystique in the upcoming movie X-Men: First Class.
"Nothing's sacred anymore. Those girls and I got so close. They were painting me naked every day for months. It was kind of like going to a really bizarre sleepover." she said.
"It's what you guys imagine we do: one naked girl and seven pairs of hands all over her." she added.
The actress also had to stick to a tough diet, and work out for two hours a day
"It was awful. I was hungry for five months. I'm still pissed about it," she said. "I'm slowly working my way back, because I have to be able to eat like an "hole."
