Winehouse vows to stay off alcohol

British singer Amy Winehouse has promised fans she will keep away from booze - but only before she performs at concerts.

The 'Rehab' hitmaker, who was recently arrested in Norway for marijuana possession, told her tour organiser on Monday she will stay away from alcohol until after her gigs.

An insider says: "This tour started pretty much as the last one ended. Berlin was a difficult time for everyone and we thought it was going to turn into another tour full of drunken and missed shows.

"But she's now said that she will not drink before her gigs for the rest of the tour. She stuck to it in Amsterdam, amazingly, and gave her best show of the tour yet. Everyone just hopes she keeps it up."

The European tour ends in Manchester, England on 13 December.
