As far as public persona or whatever, Brad Pitt is attending AA meetings, and I believe they're open public meetings. I live in LA and have friends who've run into a number of celebrities at AA meetings, there's one in West Hollywood that's notorious. Brad also has been very public about his drinking, the problems its caused him, and his sober journey. He has two HUGE movies out right now.
Not sure how much more "public persona" you can get than that. I'm sure a few people will judge him for having been an alcoholic, but I suspect that far FAR more respect him for his honesty and bravery.
