You may recognise gorgeous French model Marine Vacth from Yves Saint Laurent and Chloe campaigns now she's starring in Jeune et Jolie, a film from renowned director Francois Ozon (8 Women, Potiche).
The 22-year-old puts in a luminous performance as Isabelle, the 'young and beautiful' teen of the title who decides to become a prostitute in Paris.
Isabelle is hardly destitute: she has a caring, comfortably-off family and can afford to pay for her studies.
So why the trick-turning? It's this question that keeps Jeune et Jolie so intriguing as we try to second guess this mysterious young mademoiselle who meets men in hotels for sex.
There's plenty of character humour to entertain, and the kind of vicarious thrils that made The Secret Diaries Of A Call Girl a guilty pleasure, though the subject of prostitution is not to be trivialised.
Meanwhile Marine holds the attention throughout: this is one model-turned-actress to watch.
Jeune et Jolie is in cinemas now
