London, Aug 4 : Former pop singer Billie Piper, 25, has revealed that she has shot her sexiest 'fetish' sex scene ever for the second series of 'Secret Diary of a Call Girl'.
She says that her character Belle de Jour offers fetish sex in the new series.
"There are some very unusual fetishes coming up. As long as they've got the right money, Belle will make anyone's fantasy come true for them," British tabloid The Sun quoted her as saying.
The second series of the show was not easy to film as Billie got married to actor Laurence Fox, 29, and is now seven months pregnant with her first child.
"I needed two body doubles in the end. As I got more and more pregnant I began to gain weight so it looked silly having a really skinny body double," says Billie.
She insists that the series has a very human message.
"If people can watch The Sopranos and identify with mafia boss Tony, who's a murdering gangster, then they should be able to understand where Belle's coming from," she added.
