Amy Winehouse isn't all better. 

Despite news that the singer was winning her battle against substance abuse, the opposite was clear to fans in Belgrade, Serbia on Saturday. In a video of the concert swirling the web, Winehouse stumbles across the stage during the show, unable to fully stand at times, according the Associated Press.

Like Whitney Houston experienced not long ago when she gave less than expected, patrons began walking out during Winehouse's performance. A representative for the singer in London announced that Winehouse has turned down her fee for the Serbian show. This situation sends a clear message that Winehouse's upcoming dates would most likely go unfulfilled.

The Back To Black singer's next concert is scheduled for Bilbao, Spain on July 8 however many believe the show will be canceled. The Brit's European run was slated to end in Bucharest, Romania, on August 15.
