The "Where Are U Now?" singer went to Twitter to break the news, swearing up and down that he'll do whatever he can to make up the let-down to the ticket-buyers.
"UK beliebers I'm going to make this up to you soon," he tweeted with an attached statement.
"To all my UK beliebers," the statement read, "Due to an unforeseen issue I will be unable to perform at the Fusion Festival on August 28th. I support the Prince's Trust wholeheartedly and I am deeply disappointed I won't be able to perform. I look forward to the opportunity to give my UK beliebers a great show in the near future, and hope to honor my commitment to Trust at that time."

Uhh...what the what?! That would've been the first time Justin has played in the U.K. in over two years, just sayin'. But don't think JB isn't ready for all the rumors and backlash...
"And now the Uk press will start to tear me apart. Comes with the job. Love u guys regardless and I will make this up to you," he went on.
He then tweeted he "will see u soon UK," but so far, no announcements have been made for a rescheduled performance. To try to make nice, Justin did treat fans to another surprise a few hours later.

"Back to the studio," he wrote. "Need to finish this album. Might have a name."
