"I feel very protective of younger actresses because it was so hard for me in the business," she said of Fox, 26. "I wanted to get it over [with] as quickly as possible, because I knew it was uncomfortable for her, probably - or maybe not."
"But just in that situation I knew there were a lot of dirty boys around having weird, gross fantasties. And so I wanted to get her shirt back on as quickly as possible."
One of those "dirty boys," however, was not Mann's husband of 15 years, Apatow, who admitted that in spite of all his films' potty humor, he still felt "uncomfortable" about Fox's shirtlessness.
"I get so uncomfortable with even partial nudity in movies. I'll do one or two takes, and feel weird," he told Yahoo! Movies. "Megan is a beautiful woman, but she literally changes the temperature of a room when she walks in."
Luckily for him - but perhaps unluckily for Fox's many fans - partial nudity is as far as the new mother will go.
"I would never be naked," she told E! News of her movie choices down the line.
