Billie PiperBillie PiperYou might be seeing a darker, wilder side of Billy Piper.

As she may be stepping into the shoes of a high-class call girl.

Billie is in talks to play the leading role in a new TV drama Belle De Jour.

The show's about a sexy London prostitute who makes a fortune by describing her sexual acts on the internet.

The role is a far cry from Billie's more squeaky-clean screen appearance as Doctor Who's former assistant.

A production insider told The Sun: "We've been fascinated by Belle De Jour and thought it would be terrific TV.

"Billie will be great in the role because she's naturally really flirty and mischievous."

Sounds like a perfect fit.

The new series is in development and expected to hit TV screens later in the year.
