According to MJ's Blog, which has sources inside AI, the reason Simon got all over Kara is that the judges were given the opportunity to *help* their contestants with their interpretation of the Judge's song choice at rehearsal. Simon was the ony judge who showed up to assist Adam in his preparation. So, when Kara ragged on about Kris not interpreting the song well, Simon threw it in her face that she hadn't done anything to help him. And well he should have!
Kara is really getting on my last nerve. Did she actually mouth *oh no* when Kris was named to the finals? Someone thought that she did.
I think it serves them ALL right. They have been pimping Dorkey all season long. Go Kris!
