What do you mean, Justin Bieber?! The 23-year-old pop star announced on Monday, July 24, that he is cancelling the remainder of his Purpose World Tour, which began in March 2016 and was set to conclude on Oct. 7 in Singapore.

But why did Justin — whose last concert was in London on July 2 — decide to call it quits on his massively successful international tour? Well, according to the Canadian-born entertainer, he was simply tired after more than 100 shows across six continents.

“I’ve been on tour for two years. [I’m looking forward to] resting, some relaxation,” the “Sorry” crooner told TMZ while hanging out with friends in Santa Monica Beach on Monday. “We’re gonna ride some bikes.”

While his legions of Beliebers are understandably sad about the abrupt end of his tour, Justin offered his sympathy to fans who won’t get the chance to see him perform live. “I love you guys. I think you guys are awesome,” he said. “I’m sorry for anybody who feels, like, disappointed or betrayed. It’s not my heart or anything, and have a blessed day.”

In a statement shared on his official website, Justin’s management said that the tour ended due to “unforeseen circumstances,” but insisted that he is “grateful and honored” for the experience. "Justin loves his fans and hates to disappoint them,” his team wrote.

Despite his apology, ticketholders have taken to Twitter to express their disappointment in JB. “Beyond upset and crushed that @justinbieber cancelled his tour??????,” one fan wrote, while another tweeted, “Justin Bieber just cancelled the rest of his world tour ask me how many tears are coming out of my eye sockets right now.”
