Babyshambles star Pete Doherty has finally explained why he scrapped with RAZORLIGHT frontman JOHNNY BORRELL in 2005 - insisting he was jealous of the singer's rising fame.

The pair famously fell out over an incident at Leeds musical festival in England in 2005, with Doherty rumoured to have punched Borrell square on the nose during the brawl.

And Doherty has now admitted to starting the fight, revealing he was infuriated by Borrell's band becoming more successful than his own.

He says in new biography, Beg, Steal or Borrow; The Official Babyshambles Story, "I was unnerved and angry about the way he'd become successful. He was saying s**t about me in the press. In the end we just got round there and it was handbags at dawn.

"Johnny's going, 'You c**t, I've been boxing on Holloway Road,' I just went: 'Have some of this, ' and put one on him (punched him).

"I caught him with a f**king stonker. His nose went like a ripe tomato. He wore sunglasses for a month."
