She pulled the strings of millions of peoples hearts at the memorial. Like it was said everywhere, for most people who were not Michael fans, when she talked, it humanized him. He was no longer Michael the entertainer, no longer the guy who everyone talked crap about. He was this little girls father. And she made everyone see this. She will always be known for that. So as an American princess? I don't know, but she will be known as the little girl who lost the best daddy in the world.
On a side note, IF she does ever go the LMP path and try to sing, please don't let her come out with a song like "Lights Out" ugh!
