The Queen in Paris, and a puzzle

I have heard that French law is very strict when it comes to publishing photographs of people, even if it's just street photography or in a bit of art. Henri Cartier Bresson would have had his socks sued off if he were unfortunate enough to be photographing nowadays. So it seems even odder that Hotmail managed to use the Queen's portrait in an advertising campaign promoting a commercial product all over Paris. How on earth did they manage to persuade her to sign the model release?
