N-Dubz star Dappy launched into a Twitter rant on the X Factor, saying it will never produce a genuine artist.

The 24-year-old rapper, bandmate and cousin of new judge Tulisa Contostavlos, tweeted yesterday:

"...F*** X factor and every thing they stand for, no real original music or artist will ever come off that fake show exept Leona Lewis..NaNa."

Dappy showed support for Tulisa's new X Factor endeavour saying, "I love tulisa and I'm so proud of her."
