SEX PISTOLS star John Lydon has hit out at troubled rocker Pete Doherty's substance abuse and tabloid domination - slamming the singer as a joke. Lydon, better known as JOHNNY ROTTEN, accepts the appeal of publicity but urges the Babyshambles frontman to curb his wild ways to salvage his IQ. He says, "Every season there's a new one. Come on, he's just trying to do whatever he's trying to do and they are paying him well and keeping him in all the gossip magazines. "He's kind of got himself caught in his own trap and the danger there is becoming a parody. "Honestly, have a look at Ozzy Osbourne. Is that in your future? Rich and dumb as a doorbell - I'd rather be poor and bright."
