Carla Bruni might be a multimillionaire aristocrat, former supermodel and French president's wife but let's not forget that her day job is to rock modern society to its foundations with her own brand of breathy folk-pop.

So it is perhaps no surprise that France's free-spirited first lady has a song on her new album called Ma Came (translation: my junk, or my dope) in which, speculation has it, she sings: "My guy, I roll him up and smoke him." The album will be called Comme Si de Rien n'Etait (As If Nothing had Happened) after a picture by Bruni's photographer brother, who died two years ago.

She has written 14 tracks herself but her agent has said that 95% of the songs were written before she met Sarkozy. This leaves critics looking for the bits inspired by the president. The album includes a cover of the song You Belong to Me, once covered by Bob Dylan, which will bring back memories of the couple's highly controversial public cavorting on Middle Eastern mini-breaks: "See the Pyramids/Along the Nile/Watch the sun rise/On a tropic isle/Just remember darling/All the while/You belong to me."

Intriguingly, Bruni has also co-written a song with France's ageing enfant terrible, the novelist Michel Houellebecq, based on a poem from his science-fiction novel about cloning and "neo-humans", The Possibility of an Island.
