Keane frontman TOM CHAPLIN has challenged Serge Pizzorno to a drinking contest - after the Kasabian guitarist accused the singer of attending rehab last year (06) for a "publicity stunt". Chaplin attended the Priory last August to conquer his alcohol and drug addiction, but Pizzorno accused the singer at the time of faking it. Now Chaplin has hit back, saying, "That would have been a dirty and pointless publicity stunt. Kasabian... if you pitched me into a battle to see who could get more wasted with any of those guys, I'd definitely come out of the winner. Or loser, depending on which way you look at it. "I had a good capacity for getting trashed. I was no lightweight."
