Two of Justin Bieber's recent shows have been postponed after the singer tested positive for COVID-19.

Bieber was scheduled to perform in Las Vegas Sunday, part of his Justice World Tour, but the show was postponed due to positive COVID results "within the Justice tour family," according to an announcement on Instagram.

A representative for Bieber confirmed to ABC News that Bieber tested positive for COVID-19. The show will now take place on Tuesday, June 28; tickets for the original show will be honored.

"Due to positive COVID results within the Justice Tour family, we will unfortunately have to postpone Sunday’s show in Las Vegas," a statement from the tour said. "Justin is of course hugely disappointed, but the health and safety of his crew and fans is always his number one priority. The tour launch in San Diego was a massive success, and Justin is excited to bring this spectacular show to his Las Vegas fans as soon as possible."

The tour's Instagram account shared another announcement on Sunday that Bieber's show in Glendale, Arizona, scheduled for Feb. 22, will also be rescheduled.

The new date for the show is June 30.

The Justice World Tour, featuring Jaden Smith and TEO, launched Friday in San Diego and is set to run through March of 2023, visiting 20 different countries in 13 months, including Brazil, Chile, South Africa, Israel, Australia and New Zealand.
