In British English it could in theory be used of anyone -- and in the past I think it was -- but nowadays it has an old-fashioned sound to it, with the one exception of the sensationalist tabloid headline, where I guess the subject would normally be a well-known person. I suppose the headline writers like the term because it's short and provocative.
