Justin Bieber has postponed all remaining U.S. tour dates for the Justice World Tour as he continues to battle with Ramsay Hunt syndrome.

A message posted on the Justice Tour Instagram page last week read, “In light of Justin’s ongoing recovery, the remaining US Justice Tour shows scheduled for June and early July will be postponed. Justin continues to receive the best medical care possible, is upbeat about his recover, and is looking forward to getting back out on the road and performing for his fans later this summer.”

According to the post, new U.S. dates will be announced shortly.

The singer revealed in a recent Instagram post that half of his face is currently paralyzed because of the syndrome.
