Billie Piper pregnantBillie Piper has made a right meal of her sex scenes.

Well actually, that's to say she'd rather have a meal than a sex scene.

Confuddled?

She struggled to perform in her raunchy new drama - because she was so hungry.

Billie, who's expecting her first baby next month, again stripped off for the second series of ITV2 hit Secret Diary Of A Call Girl.

But all she could think of was her tummy.

She said: "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."

Billie as Belle De JourAnd her blooming body shape was hard for the crew to work around as she played high-class hooker Belle de Jour.

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

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

Well scoff what you like now, Bill - you're going to need your strength to get the little mite out.
