Pete Doherty has launched a scathing attack on former best friend CARL BARAT, insisting he supplied him with crack and is now "in the worst band" of the two. Barat famously kicked Doherty out of the band The Libertines in 2004 because of his drug addictions, but the Babyshambles frontman now alleges Barat shared his hedonistic ways. He says, "He used to get me good crack but now he's in the worst band and needs to sort it."
