Uh...uh...different planet you live on.
Singer and Allen had accusations without evidence, at least none that has been made public.
To the greater public, Chris Brown is irrelevant except for poor-taste jokes.
Some folks are Teflon, though - grant you - but many more aren't.
Let's talk about Mel Gibson, who is practically unemployable right now in mainstream Hollywood. He will never be a leading man again. That's a lot closer example to Johnny Depp - the actor that men and women both like, that seems like a great guy to have a drink with for the fellas and for the ladies is handsome, slightly-edgy bad-boy with a heart of gold so they aren't threatening.
I won't say he's finished - but this is something that could easily haunt him the rest of his career. Given that he already has been labeled as statistically the most over-paid actor in Hollywood, the performance of this new Alice film in some question right now, and this new scandal - particularly as we have photographic evidence of this incident, to go with the allegations that this has been an ongoing issue...he certainly won't be as beloved as he once was.
