Billie Piper has exposed that actual hookers assisted her get ready for her newest TV role as prostitute Belle de Jour. 'It has been a real eye-opener filming this series,' says Billie, 24. 'I met a few call girls to learn about how to play Belle. I couldn't be prudish and shy – not playing a woman who sells her body. 'I've learned one or two things to take home. I've always been intrigued about swingers' parties.'
And Billie will shock audiences when she says c**t in the drama which has obscene language and raunchy content. We've had a look at a clip from the series – and it's X-rated stuff. You have been warned!
