Sam Smith has canceled his Australian shows after being diagnosed with a hemorrhage to his vocal cords. The singer cannot perform until he has recovered, according to doctor's orders.

Smith shared the news on his Instagram with a heart-wrenching message.

“I am deeply, deeply saddened to tell my Australian fans, I have to cancel my Australian tour,” Smith wrote. “I have been vocally exhausted for a while now however last night in Sydney I had a small hemorrhage on my vocal cords. The doctors have told me I need to fully rest until my vocal chords have healed, otherwise this could become a huge long-term issue. I am so sorry to all who have bought tickets, I truly am. This kills me.”

Shows in Sydney, Melbourne, Adelaide and Perth have been cancelled, along with a TV appearance at the Logie Awards, according to Billboard. He started touring on Saturday. The tour promoter is working to reschedule the dates for a December tour.

"I love you all and I am so sorry x please keep your eye on my Facebook/Twitter/Instagram for re arranged December dates," he wrote.

A day before canceling his Australian tour, he got a tattoo for his fans -- his "little sailors." On Monday, he shared a pic of his anchor tattoo.
