A cursory search proved fruitless....the Artist Management agency's address published at IMDB is available only to paid subscribers (the stoat has better things to spend money on) and I'm guessing that like most other celebrities, this one is protected from the unwashed masses by numerous layers of security and management to the point where any such meaningful photos or letters would never get within miles of her.
I’m thinking maybe we should send them to her book publisher(s).....I think Random House is one.....????
