After an electric opening night, Justin Bieber's tour has hit a speed bump ... we've learned the singer has tested positive for COVID-19, and at least one concert date has been postponed.
A rep for the singer tells TMZ Justin found out Saturday he had COVID, but thankfully is feeling OK. Justin was supposed to perform at T-Mobile Arena Sunday in Vegas, but now that show has been moved to the summer.
Justin is then supposed to stop in Glendale, AZ for a show Tuesday before hitting The Forum in Los Angeles Thursday. We don't know when he contracted the virus, so it's unclear if those concerts will also be put on ice.
Bieber's had a busy last week ... performing at The h.wood Group and REVOLVE's Super Bowl Party last Friday before hitting the road.
