All moms and dads are multi-taskers, but Hailey Bieber and Justin Bieber juggled having their first baby, son Jack Blues Bieber, with a fresh round of rumors about the state of their marriage.

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.
