Justin Bieber has postponed the remainder of his summer North American tour as he continues to deal with Ramsay Hunt syndrome, which has left one side of his face paralyzed. "Justin continues to receive the best medical care possible, is upbeat about his recovery and is looking forward to getting back out on the road and performing for his fans overseas later this summer," tour promoter AEG said on Twitter. Information about rescheduled dates and refunds is forthcoming. Bieber announced his condition in a June 10 Instagram post, saying, \u201cthis is pretty serious, as you can see. I wish this wasn\u2019t the case. But obviously, my body is telling me I need to slow down.\u201d The singer's Justice tour has already been postponed several times due to the COVID-19 pandemic. As of now, it is scheduled to resume July 31 in Lucca, Italy, and run through Dec. 7 in Auckland. A 2023 leg is due to begin Jan. 11 in Amsterdam and wrap March 25 in Krakow, Poland.
