He wrote: “Today, I can no longer sing ‘Barbara’ because a woman who wanted to sing ‘Barbara’ with me accused me of rape. I finally want to tell you my truth. I have never, ever abused a woman.
“Hurting a woman would be like kicking my own mother in the stomach.
“A woman came to my house for the first time, with a light step, going up to my room of her own free will. She says today that she was raped there. She came back a second time.
“There has never been any coercion, violence or protest between us. She wanted to sing Barbara’s songs at the Cirque d’Hiver with me. I told him no… She filed a complaint.”
The Life of Pi actor also addressed allegations of sexually inappropriate behaviour on set and insisted he was simply “behaving like a child who wanted to have fun”.
He wrote: “I’ve often done that which others wouldn’t dare to do: pushed limits, shaken certitudes, habits on the set between two takes, between two tensions… to get a laugh.
“Not everyone laughed. If, in believing to live the present intensely, I hurt, shocked someone, whoever it was, it was never my intention to hurt, and I beg you to excuse me for behaving like a child who wanted to have fun in a gallery.”
Arnould’s lawyer, Carine Durrieu-Diebolt, said she was “shocked and scandalised” by the letter.
She told radio station France Info: “Mr Depardieu says he is exposing his truth, but it is certainly not Charlotte’s truth and it will certainly not be the one that will be upheld by the courts.”
