Kate Winslet wore a pubic wig for ‘The Reader’

Kate Winslet wore a pubic wig for ‘The Reader’.

The Oscar-winning actress had to bare all for the Holocaust movie and producers took measures to ensure her body was consistent with the era.

She told Allure magazine: “I had to grow the hair down there. But because of years of waxing, as all of us girls know, it doesn’t come back quite the way it used to. They even made me a merkin – a wig - because they were so concerned that I might not be able to grow enough.”

Despite her embarrassing confession, Kate has previously admitted she had no problem filming sex scenes with 18-year-old co-star David Kross.

The 33-year-old actress explained: "It was the same as shooting any other scene of that nature. A scene with that level of intimacy involving nudity, you know, it's always nerve-wracking, and you really have to rehearse those scenes so that everybody knows exactly what's going on. He didn't need that much looking after."

The ‘Revolutionary Road’ star has been vocal about stripping on screen, insisting husband Sam Mendes doesn’t mind if it is vital to the role.

She said recently: "Of course Sam doesn't get jealous. I'm not a porn star. I'm not walking out there and actually having sex with other people for my job. He doesn't get jealous at all, not in the slightest. It's really not a big deal.

"I feel that any level of nudity in films that I have been a part of has been absolutely relevant and actually enhanced the story."
