Jealous wife Billie Piper

Billie Piper would "find it hard" if her actor husband stripped off for work.

The British actress - who plays prostitute Belle Du Jour in UK TV drama 'Secret Diary of a Call Girl' - is surprised at how easily spouse Laurence Fox copes with her baring almost all on screen, as she thinks she would get jealous if he landed a racy role.

She 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."

The 27-year-old star - who met Laurence when they starred in the play 'Treats' in 2007 - said it was her husband who convinced her she could get her figure back into shape after giving birth to their son Winston, now 15 months.

She said: "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."
