Earlier this month she checked out of rehab and was given the go ahead to embark on her European tour.But it would seem that Amy Winehouse has spectacularly fallen off the wagon as her Serbian fans found out to their horror last night.
The singer was booed as she took to the stage in Belgrade on the first leg of her 12-date stint, and looked intoxicated as she stumbled around the stage.
An hour after she was due to arrive on stage, after being introduced by one of her backing singers, she staggered on and made her way to the back to hug one of her guitarists.
Wearing a short green and black dress that accentuated her cosmetically-enhanced breasts, she sat down on one of the speakers and adjusted her shoes while her concerned backing singer asked if she was ok and steadied her back to her microphone.
Amy, 27, looked confused and then took off one of her shoes which she threw on the floor before walking unsteadily over to her microphone.
After missing her cue a couple of times, she proceeded to deliver a half-spoken and mumbled version of her song Just Friends, her last release back in 2008.
Halfway through, slurring her words which she had difficulty stringing together, she told the crowd at the city's Kalemegdan Park: 'Let me bring the band introduction.'
But then she tried to continue singing the song, smiling all the while, seemingly oblivious of how she was coming across to her fans.
