Amy Winehouse has axed her entire comeback tour and will not be performing onstage again until she can "return to her best".
The troubled Rehab singer left fans aghast after her disastrous tour opener in Serbia at the weekend (18-19Jun11), where a seemingly drunk Winehouse stumbled around the stage, slurred her songs and stormed off several times.
She was set to tour Europe to play 12 shows in a bid to bolster her comeback after a five-year gap, but her management has now pulled all her further gigs.
A spokesman for the star adds Winehouse won't return to the stage until she can perform to the best of her ability.
A statement reads, "Amy Winehouse is withdrawing from all scheduled performances. Everyone involved wishes to do everything they can to help her return to her best and she will be given as long as it takes for this to happen."
Winehouse's battle with substance and alcohol abuse is well known - her most recent rehab stint came only last month (May11).
