No pop star is a good or bad role model if you teach your daughter to be independant, strong minded, and stronged willed. Entertainers are only entertainers and only people, they have flaws and while she apears to be fine now, the vast majority of child celebrity will eventually end up messed up in some way or another, because it's not a normal or helthy environment for a child. I say say let her enjoy healthy entertainment, but don't let her idealize anyone, except the person(s) or thing(s) in whatever you religion may be.
