Billie Piper is back as Belle in a second series of Secret Diary Of A Call Girl on ITV2.

The series that achieved record audiences of more than two million in 2007 returns to the channel for a further eight episodes in September 2008.

Based on the best-selling, real life diaries of an upmarket escort, SECRET DIARY OF A CALL GIRL allows us a deeper look into the world of the glamorous and intelligent Belle de Jour (Billie Piper) – Hannah to her family.

Belle is now a high-class independent escort.

Unintentionally befriended by the bubbly but clingy Bambi (Ashley Madekwe – Trial & Retribution, Drop Dead Gorgeous), Belle finds herself an unwilling mentor to this wannabe call girl. And while her best friend Ben (Iddo Goldberg), the only person who knows about her secret life, seems to be settling down into domestic bliss, Belle is throwing herself into her work.

But then Hannah meets Alex (Callum Blue – The Tudors, Dirt), the handsome doctor who she mistakes for a client in a hotel bar. Belle faces the most difficult question of all – can you keep having sex for money if you’re falling in love? Will the girl who thinks she has it all ever really manage to have a relationship?
