The song, which is called 'Lady Rouge', isn't a bid for chart success, however. Instead it is the soundtrack to the latest advert for French fashion house Dior.
Marion, who is the face of the label's Lady Dior handbag range, has recorded the vocals for the track and will also star in the ad. We hear that she will play a girl who works by day and sings by night, and she will appear from behind a velvet curtain to sing.
