India, July 26 -- Singer Justin Timberlake faced backlash after a viral video showed him barely singing his hit Can't Stop the Feeling! at his recent Romania concert. The 44-year-old, currently on the European leg of his Forget Tomorrow World Tour, performed at Electric Castle in Transylvania last week. This concert is his first-ever show in Romania. Throughout the performance, Justin can be seen gesturing to the crowd to sing, as he chimes in with a few lines and minimal dance moves, letting the chorus play out in the background. Social media users slammed the pop star's low energy and lack of effort in the performance. Justin is yet to address this backlash. htc...
