A DJ was performing at a nightclub when he was told Justin Bieber was at the venue and wanted to perform, an impersonator joined him onstage.

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.
