"I was an eager canvas," Rebecca told ET. "I said, 'I want to get painted again!' It only took five hours. It used to take forever. The first time I was ever painted for Sports Illustrated took 12 hours. The first time they did my makeup test for X-Men was 12 hours."
The actress wore body paint and scaly prosthetics to play Mystique in Marvel's X-Men. While the prospect of appearing nude on the big screen might bring sweaty palms to some, Rebecca told ET there was nothing unnerving about it.
"It's a funny thing. When you're painted, you feel completely covered up," Rebecca said. "You can really tell when you see our models and their body language that nobody feels naked, but they are. If nudity is your thing, we're your show."
Rebecca's husband Jerry O'Connell also seems to be fine with showing off his goodies. The actor was caught photobombing a picture of the couple's twin daughters Dolly and Charlie, wearing nothing but a Speedo.
