French newspaper Le Parisien and broadcaster BFM TV said the woman alleged that Depardieu assaulted her on Aug. 7 and Aug. 13, 2018 at his home in Paris. The two met when Depardieu led a master class at her school, BFM TV reported.
The actress, who has not been named, first filed a complaint with details of alleged rape and assault in August 2018 in the southern French city of Aix-en-Provence. The probe was take over by Paris investigators, but was soon dropped.
Depardieu's lawyer Hervé Temime was not immediately available for comment, but he has previously said that the actor "absolutely denies any rape, any sexual assault, any crime."
Depardieu, 72, is among France's most well-known and controversial stars.
He has appeared in 200 films over six decades and is among a few French actors who have made a name for themselves in Hollywood. He won a Golden Globe for his performance in "Green Card," a 1990 English-language romantic comedy co-starring Andie MacDowell.
His first big hit in France was "Les Valseuses," ("Going Places"), Bertrand Blier's classic farce about two wandering thugs.
Before crossing the Atlantic to star in "Green Card," Depardieu played an array of roles, ranging from Jean Valjean, the thief-turned-saint in "Les Miserables," to Christopher Columbus.
In 2014, he played the leading role in "Welcome to New York," the film inspired by the life of Dominique Strauss-Kahn, the former director of the International Monetary Fund who was accused in 2011 of sexually assaulting a hotel maid.
