A doctor informed the singer that it was imperative that she take at least a few weeks of total vocal rest, or else it might permanently damage her vocal chords.
“I’m really frustrated. I was hoping with a weeks rest I’d be better to sing again straight away,” Adele said in a message posted on her Web site on June 3. “However, there is absolutely nothing I can do but take the doctors advice and rest some more.
Adele had already had to cancel five concerts of her tour in North America. She canceled the remaining nine dates that were scheduled.
The 23-year-old singer’s album, titled “21”, surpassed Lady Gaga’s Fame as the biggest-selling digital album in the U.K., becoming the best selling album of the year. It sold nearly two million copies in North America.
The statement released Friday said it is possible that the concerts will be rescheduled.
