Billie Piper's hunger pangs made playing sexy hooker scenes impossible!

London, Sept 2 : English actress Billie Piper, 25, has revealed that she found it very difficult to play a call girl in her raunchy new drama, as she was feeling hungry all the time.

Piper, who is pregnant and expecting her first baby next month, still strips for her role in the ITV2 hit 'Secret Diary Of A Call Girl', but the only thing she can think about throughout the filming, is her grumbling stomach.

"Being pregnant and filming scenes where you're having to be sexually provocative - when all you want to do is sit in a corner and eat - that was hard for me," the Sun quoted her as saying.

Her hunger pang was not the only thing she had a problem with, but also her baby bulge that the crew found hard to disguise as she played the part of high-class hooker Belle de Jour.

"By the end it was really tricky, I was showing big time," she said.

"I wear tight clothes in the show, so it's obvious. Plus I was eating like a horse!" she stated.

With the new series starting soon, Piper, who is married to actor Laurence Fox, 30, is happy that she can now concentrate on motherhood.

"That's a relief because it means I don't have to think about my career," she added.
