I'm not really that easily bothered, but I was actually found her performance disturbing and hard to watch. No matter how sexy and nasty she tries to look.. she still just "looks" like a 13 year old anorexic with issues acting out. Her keepers should be fired for allowing that crap to go on stage. I also agree it's really just uncreative, badly choreographed copy-catting. It's pathetic, and embarrassing.
If you'd bought a ticket to one of her concerts.. OK whatever you paid to see her, but to toss that out there at an awards ceremony full of random folk... totally inappropriate.
The really sad thing..it's all just publicity for her. There won't really be any long term repercussions and she'll keep making millions. Hollywood loves a train wreck too much to ever look away.
