London, Sept 19 : Actress Billie Piper revealed that she is nervous about playing the role of a prostitute called Belle De Jour in a new eight-part ITV2 drama, The Secret Diary Of A Call Girl.

The actress fears how people would react to her new role, especially after the popular tomboy role of Rose Tyler in Doctor Who series.

“It’s quite scary thinking people are going to see you in that way for the first time and that people may treat you slightly differently,” Daily Express quoted Piper, as saying.
