I just watch this by video, and although I wasn't blown away, I saw something... I think Christina Aguilera could be one of the biggest "LGBT" star that has ever happened, if she started performing the way she does in this video. It gave off strong "Queen" vibes.

I'm a huge Christina fan, love her to death! But she lost her ambition years ago...doesn't release much stuff and when she does she doesn't promote. She could be huge if she wanted to, she has the talent, the looks and the style, but I think she just doesn't care much anymore.
