Justin Bieber has canceled one of his upcoming concerts in Portugal.
The concert's promoter posted a message on their website that promised refunds to the fans.
It said, "Due to unforeseen circumstances, Justin Bieber was forced to cancel the second operation, in Portugal, on 12 March. The Canadian singer is eager to play for the Portuguese fans on 11 March."
The news of his canceled concert comes on the heels of a pretty bad week for the pop star.
The "Beauty and a Beat" singer received flack for starting a show two hours late, before collapsing on stage the next night.
