Why is there a chubby girl singing on my tv?

I don't know why I'm watching it because it's shit, but I am watching the pregame show to the first football game of the season (for you Europeans, I am referring to American football). Anyways, they start the show off with Kelly Clarkson singing some song she sings, and I have to say, she's pretty chubby. Now, I have nothing against chubby or ugly people being musicians, but what's the point in pop music? None of these people write their own songs or music, they just sing them. Sure Kelly Clarkson has a good singing voice, but you can't tell me the people who write her music for her can't find someone hotter who they can teach to sing. Now, if Kelly actually writes her own music, I do apologize, and I say carry on, chubs! But I really doubt she does, and I'm too lazy to look it up. Anyways, I just find it odd that people would write songs for her when they could do the same for hot people who will draw more of an audience. If you have no creativity to write your own music and the only thing you can do is sing, then you better be hot, otherwise get out of music. That's all I'm saying. So, my message to Kelly Clarkson: either write your own damn songs, or get off the stage! Is that too harsh?
