British actress Billie Piper has been picking up tips from a dominatrix to prepare for her latest role as a prostitute.
The 'Doctor Who' star will play a high-class hooker in a new television show that's an adaptation of the book 'Belle de Jour'.
"They do have a dominatrix on set to advise. It's about prostitution and they want to get it right," a show spokesperson has revealed.
'Belle de Jour', whose real identity is unknown, cashed in after posting intimated details of her sex life online.
