Amy Winehouse was pushed on stage by bodyguards to perform at a festival in Serbia at the weekend, it's been reported.
The singer was booed throughout her performance in Belgrade, with allegations that she had been drinking before arriving on stage.
Ana Zoe Kida, who also performed at the festival with her band Zemlja Gruva, claimed Winehouse was pushed against her will on stage.
"Four British bodyguards simply pushed her to step up on stage,” she told The Sun. "She did not want to and was making a scene trying to escape them.
"It was distressing to see, she obviously needed help."
On Tuesday (June 21), Winehouse's management confirmed that the rest of her European tour had been cancelled.
