I heard a bit of this on the news, too. Its really sad.

I didn't see both girls, just the one who did the lip-syncing, but I heard the real singer had "crooked teeth"(not sure if this is valid). Sure, crooked teeth aren't considered an aesthetic aspect by most, but it isn't a good enough reason to deem someone as not being pretty. Like I said, I haven't seen the real singer, but I am sure she looks cute enough... she is seven, for crying out loud! It seems like a good portion of society's view on looks is a bit warped these days.

I really do feel sorry for her.
