How often do you believe celebrities get away with Boorish, obnoxious, or rude behavior because they are famous?

I am sure if you ask just about anyone to name an obnoxious, rude, arrogant celebrity, they will produce a name. Acts and behaviors certain celebrities do often seem to go unchallenged; the obnoxious behavior often even elevates the popularity of the celebrity who had done it, or is doing it. As for the US, can’t say what it is like in other nations, have we gotten so smitten with the famous that they can do things and act in way we would blast others for doing, that we find it cute, interesting or noteworthy?
