BILLIE Piper leans on a lamppost as she totters in high heels in her TV role as a vice girl.

The 27-year-old actress was back as escort Belle de Jour to film the final series of ITV's Secret Diary of a Call Girl.

Heavily-dolled-up, Billie drew admiring glances from passers-by on a busy London street as she leaned into cars pretending to punt for business.

An onlooker joked: "I've never seen a prostitute looking as incredible as that - especially not in the middle of the day!"
