Charismatic JACKASS star Johnny Knoxville is desperate to write a novel - but consistently finds his literary plans thwarted by his love of alcohol.

The 34-year-old confesses a fondness for whiskey but often regrets its crippling effect on his creativity.

He says, "I would like to go back to writing, but whiskey always gets in the way.

"I ruined myself on Tennessee whiskey by the time I was 15. Whiskey usually brings out the best or worst in me."

And THE DUKES OF HAZZARD star is similarly anxious about the damage a writing career could do to his Hollywood reputation, according to US gossip site The Scoop.

He says, "I've started writing a novel, but when you hear about an actor writing a novel, you want to shoot yourself."
