Ananova:

Welcome to a flurry of ponderings, folks.

This one has even Showbiz Sherlock stumped.

Yup, he's furrowing his brow big time in addressing the killer question: is Billie Piper pregnant or not?

We think it's high time the cat came out the bag - if indeed there is a cat (or baby - this is getting confusing) inside.

Cos more and more pieces of the baby jigsaw keep on flying our way.

The pregnant rumours kicked off when pics of Billie and hubby Laurence Fox frolicking on the beach together emerged last month.

Bille's tum appeared suspiciously rounded which got us thinking with our baby hats on.

Then some further goss did the rounds in the media that Billie's friends had confirmed the news.

And now, a British tabloid are alleging that Billie will have a body double for her role in the new series of The Secret Diary Of A Call Girl, so she can avoid baring her preggers figure.

"This was a mutual decision," a TV insider told The Daily Mirror. "The double won't be used all the time, only when they have to, for example, for any nude scenes.

"It's whatever she (Billie) finds appropriate being pregnant. This has to be taken into account."

Very interesting.

And to deepen the confusion still further, when Sky Showbiz contacted Billie's peeps for a comment on the preggers goss, the lady we spoke to acted rather mysteriously.

First off, she said she wasn't the right person to speak to, and then after a bit of a silence admitted that she "wouldn't know" about Billie being preggers.

After a bit of prodding on our behalf, she said that Billie's proper agent probably wouldn't know either.

A bit different from the usual "no comment", don't you think?

We'll wait with baited breath for any further hints.
