London, Feb 5: Billie Piper has admitted that she becomes desperate for a shower after filming sex scenes for `Secret Diary Of A Call Girl'.

"There is a part of me that thinks: ''I have to go home and feed my son now, and I''m going to need several showers before that. And a lot of praying," The Sun''s Buzz magazine quoted her as saying.

The 28-year-old, who plays the role of a high-class escort Belle de Jour in the ITV2, also confessed she worries about what son Winston, two, will think of the steamy show when he grows up.

"I just hope I raise my son to become someone who''s really open-minded. And forgiving," she added. (ANI)
