Justin Bieber has let his fans down. After announcing earlier this year that he will be extending his tour to parts of Asia, the pop star has pulled the plug on the remaining dates of his world tour. The news was revealed on Bieber's official website, however, no reason was identified. Fans have taken to social media to voice their disappointment over the cancellation, with many already having purchased their concert tickets.

Shows in Japan, Philippines, and Hong Kong cancelled

Justin Bieber fans were left devastated after it was announced earlier today that the remaining 15 shows would be cancelled.

According to the official post titled "Remainder of Purpose World Tour Concerts Cancelled," Bieber decided to end his series of shows due to "unforeseen circumstances." However, the exact reason for the cancellation was not revealed.

The statement reads, "Justin loves his fans and hates to disappoint them. He thanks his fans for the incredible experience of the Purpose World Tour over last 18 months...However, after careful consideration he has decided he will not be performing any further dates."

The remaining show dates were set to take place in North America and Asia, including sold out shows in Singapore and the Philippines.

Fans react as remainder of Purpose World Tour is cancelled

While the statement did not reveal any more details about the prematurely cancelled concert series, a source revealed that Justin Bieber has been "super exhausted." He has been touring over the past 18 months, spanning 6 continents and playing more than 150 shows.

A source told PEOPLE that Justin Bieber actually likes touring, "but he’s been touring for 18 months straight and it takes a toll.”

As for the fans, they can't help but vent out their disappointment following the news. Some have already purchased their tickets to see the "Despacito" singer and some are even flying out of the country just to see their idol.

Nonetheless, Beliebers are trying to remind themselves that Justin needs some R&R.

Amid this cancellation, it was also made known recently that Justin Bieber has been banned from performing in China for the time being due to "bad behavior." Still, perhaps all the singer needs is some time to recuperate before heading back out on the road.

Justin Bieber's Purpose World Tour would've run until October 2017, though fans that have already purchased tickets for the cancelled dates will be able to get their money back.
