The "Ugly Betty" actress - who has a 16-month-old daughter, Valentina, with Francois-Henri - reportedly tied the knot in France on Valentine's Day (Feb 14, 2009).
The ceremony took place at the city hall of the Sixth Arrondissement in St. Germaine, Paris.
It has been claimed the couple - who called off their engagement last July - decided to give their romance a second try by taking two romantic breaks to the French capital late last year.
In December, Salma and Francois-Henri sparked reunion rumors after they were seen being "very affectionate" at the Dubai Fim Festival.
Salma, 43, recently confirmed she is still romancing the 46-year-old businessman - who is CEO of luxury brand giant PPR - after revealing she thinks of him when she films love scenes with her "30 Rock" co-star Alec Baldwin.
She said: "I keep telling Francois, 'I imagine I was kissing you.'"
Francois-Henri - who began dating Salma in May 2006 - is one of France's richest men and has an estimated fortune of $16.9 billion.
