X Factor choreographer, Brian Friedman has said that Diana Vickers will “rock out” this week if she sticks to the dance routine he has given her.

Brian was furious a few weeks back after Cheryl changed Diana’s song to Coldplay’s Yellow at the last minute, after he had painstakingly choreographed an energetic routine to All Saints ‘Never Ever’.

Brian told MSN: "Diana will be dancing this week. If the song gets changed and they cut her performance it will be tragic because, I can’t tell you the song but I can tell you that she’s rocking out."

He added: "Diana has a lot of natural movement. I think that the problem with her whole claw thing is that she was just trying to just contain everything so now that it will be unleashed it will be good."

Asked who he wants to win Brian said: "Alexandra, one hundred per cent."
