It's the other way around: Famous Actors should realize how random strange can be hazardous to their careers; either do not say you are exclusive or stay monogamous. Avoid crazy people (hard for crazy people not to date crazy people, but there you go).

It's better to stay with someone who knew you before you became big then to chase a bunch of starf*ckers and catch a stupid charge or get divorced or what-have-you.

Especially if you have a temper.
