Brian Friedman has threatened to quit X Factor because of disputes with Simon Cowell about the show’s direction.

Friedman, 31, is the programme’s creative director, but he is apparently unhappy with Cowell’s controlling influence.

“I’m upset,” he told The Sun. “Art is art and it shouldn’t be smothered.

“I haven’t signed a new contract yet. I need six months to clear my head.”

The American choreographer was originally hired as a replacement for Louis Walsh in 2007, but had his role reduced after one week of filming.

He also criticised Cowell’s preference for ballads, commenting: “Contestants shouldn’t be allowed backing tracks. They should sing on their own.”
