Billie Piper turns into a dominatrix in the bedroom

24 September 2007 - Billie Piper is a dominatrix in the bedroom.

The sexy actress, who plays infamous prostitute Belle de Jour in new TV series 'The Secret Diary of a Call Girl', learnt a few raunchy tricks to impress her actor fiancé Laurence Fox.

Billie told Britain's Closer magazine: "I've learnt one or two tricks! There's an S+M scene and we had a genuine dominatrix on set, which was interesting. I now know how to whip a man without bruising, scarring or making him bleed!"

The 25-year-old star says playing a high-class escort has made her interested in splashing out on sexy underwear - much to her annoyance.

She said: "I really got into underwear and high heels, which is so unlike me because, as a lot of people know, I'm happiest in trampy clothes.

Now I can't walk past an Agent Provocateur store without going in and buying something for myself. It's pathetic! I like wearing beautiful underwear because it's sly - no one knows about it, so it's your secret and you feel naughty.

But I was happier and richer when I couldn't be a**ed with all that!"
