Amy Winehouse vows to keep sober on tour

Amy Winehouse has vowed to keep sober on her new tour, she has revealed, but how right will her words be? We've heard it all before!

The 'Rehab' star had to cancel many dates off her tour calendar earlier on in the year due to her alcohol addiction, and was famously hospitalized when she did appear on stage, and then went to rehab to overcome her problem.

Last week however, Winehouse stumbled on stage in Berlin and consequently forgot half of her lyrics - her head seems not to be in the right place - causing deep concern on whether she'll make any more appearances on stage - or indeed be saved from an early coffin.

A tour insider said: "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 has now said she will not drink before shows 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."
