A Justin Bieber impersonator ran up a $10,000 bar tab after he tricked staff at a Las Vegas nightclub into believing he was the Canadian pop star — even getting up on the stage for an impromptu performance. The bizarre incident took place at the five-star Wynn Las Vegas, where LA-based DJ Gryffin was performing at XS Nightclub.

His ‘team’ said he wanted to perform ‘Sorry,’” the DJ performing wrote in a video. “Little did I know I was about to be sorry.”

A Justin Bieber impersonator used his pop star-like look to his advantage over the weekend as he performed for a packed nightclub — and tricked the headlining DJ, Gryffin — at the Wynn Encore resort in Las Vegas.

“After an elaborate and multi-step ruse by him and his advance team, a Justin Bieber impersonator was granted access to the XS stage,” a Wynn Las Vegas spokesperson told SFGATE via email Tuesday. “As soon as the error was recognized, he was removed from the resort and denied future entry.”
