Sources say the Hollywood stars tied the knot at the Chateau des Conde, a Renaissance chateau in the Burgundy countryside about an hour's drive south of Paris.
The complex includes a chapel where a local mayor performed a brief ceremony in front of family and friends before they all partied long into the night.
"White marquees were put up around the grounds and everyone was very discreet because it was a show-business wedding, but generally it was pretty down-to-earth," said a source at the chateau, which is in the historic town of Vallery.
The source added that Berry, who has been married twice before, wore a simple cream dress as she arrived in a white limousine.
Also on hand was the pregnant actress' daughter from a previous relationship, five-year-old Nahla.
More details to come. Congratulations to the newlyweds!
