Insiders told Variety last month that tour organizers delayed the start of the tour from this June to February next year.

The delay of the tour comes as a result of having to book large indoor arenas, which have different coronavirus restrictions than outdoor events amid the ongoing pandemic.

Justin was first set to hit the road in July 2020. He was to be joined by special guests Kehlani and Jaden Smith, but both dropped off the tour amid the rescheduling.
