Idiot Keaton says F Word on broadcast tv

I didn't appreciate Diane Keaton, who is a movie star I generally admire, using the F word on braodcast television. This is not the language used in my home or by my family. She should realize that this is inappropriate and that as an "icon" what she says and does is important so the typical excuse used by these stars, that "it's a free world" and "I can say what I want" doesn't really fly. If she wants to be taken seriously -- such as on the "saving old buildings" issue and "it's okay not to get plastic surgery" she should not abase and belittle herself with BAD LANGUAGE.
