the portrait made in this article lacks of fundamental informations: 1) First of all Carla Bruni is of noble descent as her family is the fanous Bruni Tedeschi, Turin ancient aristocracy with french ancestors. 2) Her father was and industry mogul and most important and Opera composer.
3) She went to France because she feared to be kidnapped by italian Red Brigades communist fighters and she enrolled at the Sorbonne. 4) You forgot to mention before Sarkozy she was married to the French philosopher Raphaël Enthoven after having been engaged with his father Jean-Paul Enthoven.
I think these few elements are fundamental to recall.
