The chart-topping singer has canceled a concert scheduled to take place in Jakarta tomorrow night due to security concerns in Indonesia.
On Sunday, three Islamic militants were executed for carrying out the 2002 Bali bombings. Prior to their deaths, the militants encouraged followers to launch more attacks.
The 20-year-old "Umbrella" star was scheduled to perform in front of a sellout crowd of 6,000 in the nation's capital.
"They said Indonesia's security is not supportive," event promoter Troy Waroka told the local press. "The concert will be postponed until January or February."
Waroka said full refunds would be made available for ticket holders who didn't wish to wait.
