Whatever it's the rules! Same thing happened to Whitney Houson! She had done some random duet the year before and wasn't considered "new"... and she's a much better singer than Gaga... so it's happened before!
When you read this scene in the book it's soooo freaking exciting! I couldn't wait to see how this scene was going to be done... after that I'm so disappointed! I hope the rest of the movie is better....
Being a guy I wouldn't touch her, but I know a few girls who would beat the shit outta her for pulling a stunt like that.
I'm glad she got kicked off.... now I just want her to get fined!!!
