The 71 year old turned out at the Cannes Film Festival in France for the premiere of her new movie Standing Tall, which opened the glitzy event on Wednesday (13May15), and she took the chance to urge other film stars to give up sites such as Twitter and Instagram.

Deneuve told reporters, "It's the social networks that prevent people from dreaming any more about stars. Their private life is displayed constantly on social networks; and some even post private pictures of themselves. I find it a pity. Being a star entails glamour and secrecy; it's hard to keep any degree of mystery nowadays."
