Billie Piper has admitted that although she used to be embarrassed when filming sex scenes for the series Secret Diary Of A Call Girl, she is much more relaxed about it now. She found that she had lost all her inhibition when filming season 4 of the series. She doesn’t mind the raunchy sex scenes and she is coming to terms with the way people view her because of her part in the series. Some people see that has something not appropriate. Belle De Jour is a character and people should stop judging the actress because of who she is pretending to be.
In the series, you can see the life of an elite escort girl and sex scene with clients. She even warned that the new series of Secret Diary Of A Call Girl will be filthier than ever.
