The actress, who portrays a prostitute in Secret Diary Of A Call Girl, has revealed that her actor husband Laurence Fox understands her stripping for the camera but insists she would not be as supportive if the roles were reversed, according to STV.
The 27-year-old said: "He's so relaxed about things like that, which is helpful as I would find it stifling if he tried to be possessive. Other boyfriends I've had would've been furious. I would find it very hard if Laurence stripped off on TV - so good on him to have the strength."
Piper also said that her husband convinced her she could get her figure back into shape after giving birth to their son Winston, now 15 months.
She added: "There were moments when I wondered what on earth I was doing and thought I should be at home feeding my baby, rather than rolling around in my underwear on a bed with another man.
"I gave myself six to seven weeks to get back in shape. I ate less and the TV production company gave me a treadmill, which I went on a lot. Breastfeeding also helped. I did manage to lose all the extra weight in those six weeks. It was really tough, but I did do it."
