You can try to contact Audrey by sending her a letter to her agency. Audrey’s agency is Art Media and her personal agent is Claire Blondel. If you want to receive an answer and an autograph you should enclose a return envelope and a stamp and send it to the following address:

Art Media
20, Avenue Rapp
75007 Paris
France

Be patient. The answer might take a little while ;)
Good luck!
