Who's bright idea was it that, every cute young girl who is on television, or is a blossoming star in movies, should also become a singer?

As well, who decided that every girl from the same subset as above, who has at least a modestly successful music career, should obviously branch out and into movie roles?

Singers should be singers. Actors should be actors. Celebrities should sit quietly in the corner until there is a movie opening, or some kind of awards show party that needs photogenic people. Do what you do best, and only do that. If you SUCK, stand quietly, let them take pictures, and stop bothering the rest of us with your lack of talent.
