Less than a month after checking out of rehab, troubled singer Amy Winehouse was booed off stage during her attempted comeback concert in Belgrade, Serbia. On Saturday night, June 18, 2011, Winehouse appeared too intoxicated to perform. She staggered around the stage, mumbled lyrics and argued with her bandmates.

It didn't take long for the crowd to boo her and heckle through the disastrous 90-minute show. Her rep told CNN that the next two European tour dates have been canceled, and in a statement to Entertainment Weekly, Winehouse's publicist said, "She would like to apologize to fans expecting to see her at the shows, but feels that this is the right thing to do." 

A local paper in Serbia called it "the worst concert in the history of Belgrade."
