Justin Timberlake received criticism for a lackluster headlining set during the Electric Castle festival in Romania.

Justin Timberlake’s performance of 'Can’t Stop the Feeling!' at the Electric Castle festival in Romania is being criticized by some fans after a viral video showed him onstage singing only a handful of lyrics while making small dance moves.

Timberlake also faced backlash in Feb. for abruptly canceling his final tour stop in Ohio after coming down with the flu. The *NSYNC alum said he was “heartbroken” that he had to cancel the concert and promised refunds, but fans still slammed him for the last-minute notice.
