Dannii Minogue has slammed Britney Spears for upsetting the X Factor contestants by refusing to meet them after her recent performance on the hit reality talent show.

The Aussie judge blasted Britney for not even saying hello to the contestants, when other acts have held a master class with them.

She told Metro: "They were genuinely excited to be in her presence and she only had to say 'Hi' to five acts.

"At that point, I thought, 'What a shame because you've just crushed those contestants'. She didn't have to be like that."

Dannii also revealed that the singer's had the judges lining up like youngsters waiting for class.

She said: "It was hysterical. We were all like little kids at the principal's office. There were so many security guards and PR people and they had to block the whole corridor before she could come out the door."

Here's the latest video by Dannii Minogue for "Touch Me Like That".

I haven't followed her career as much as I should have considering that this is a good dance song and the video's pretty cool too.

I'm absolutely shocked by the physical resemblance to her more popular sister, even her voice sounds like Kylie.
