Justin Bieber has cancelled the rest of his Purpose World Tour because of "unforeseen circumstances", his publicist has said.
The move will affect 14 dates in Asia and North America over the next three months.
Bieber has performed more than 150 shows since the tour promoting his 2015 album Purpose began in March 2016.
The tour grossed $93.2m (£71.5m) in the first half of 2017, with an average of almost 40,000 ticket sales per date.
The singer himself has not yet commented on the decision on social media, but unnamed sources told US media he was "just over it".
But a statement on his website read: "Justin loves his fans and hates to disappoint them.
"He is grateful and honoured to have shared that experience with his cast and crew for over 150 successful shows across six continents during this run.
"However, after careful consideration he has decided he will not be performing any further dates. Tickets will be refunded at point of purchase."
Most of Bieber's remaining dates were in the US, but he was also due to play in Japan, Hong Kong, the Philippines, Singapore and Indonesia.
Chinese officials said last week that the Canadian pop star had been banned from mainland China because he had engaged in what they described as "bad behaviour".
Bieber's decision comes a few weeks after British singer Adele cancelled the last two shows of her world tour on medical advice after damaging her vocal cords.
This year Malawi will host its first Hip Hop awards; dates for the event will be announced later in the year, and will feature local acts such as 3rd Eye, Dominant 1, Kenny Klips, Genii Black, L-planet, Trudocsy, Kananji, DJ Milatino and others.
The awards are aimed at celebrating the Hip Hop culture, this includes M-Ceeing, Break-dancing, DJaying, Visual Arts and Beat Boxing.
“Elsewhere in the world, people celebrate Hip Hop through Awards and festivals. We shouldn’t be the only country out of the picture,” Chirwa was quoted as saying.
“After seeing a void where much effort is put in urban music, I thought it wise to start something which will focus more on Hip Hop as a culture.
I started this idea 3 years ago but now am going full throttle,” said the event organiser Geoff Chirwa.
Malawi now joins a list of countries such as USA, South Africa and Zambia among others which have annual Hip Hop Awards and festivals to celebrate the culture.
Luis Fonsi's Despacito has become the most-streamed song of all time, just six months after it was released.
The hit single has been played 4.6 billion times across all streaming services, overtaking Justin Bieber's Sorry, which previously held the title.
"What's happened with this song is just insane," said Fonsi, who hails from Puerto Rico and sings in Spanish.
"I don't want to use the word accident because I was trying to write a hit, but I didn't plan for it to cross over.
"I just wanted to make people dance."
The 39-year-old said the global success of his song - which has reached number one in more than 45 countries, including the UK - gave him hope in the current political climate.
"I come from Puerto Rico and I live in Miami. We're living in an interesting time right now when people want to divide us. They want to build walls.
"And for a song to bring people and cultures together, that's what makes me proud."

Despacito is a sun-bleached slice of sensual reggaeton. The title translates as "slowly", referring to the speed of Fonsi's seduction technique.
It hit number one around Latin America when it was released in January, but only caught fire in the English-speaking world after Justin Bieber heard the song in a nightclub and asked to add a verse.
His version of the song - known as Despacito (Remix) - has become a phenomenon on streaming services, most notably Spotify and Apple Music. It is already the fourth most-played video of all time on YouTube, where it is rapidly closing in on the top three, all of which are years old.
The head of Universal Music Group, Sir Lucian Grainge, said the success of Despacito showed how streaming was democratising the music market.
"Streaming has allowed a song with a different beat, from a different culture, in a different language, to become this juggernaut of success and pleasure," he told the BBC.
"The industry has predominantly been English-speaking artists for the last 50 years [but] streaming will continue to open up music from Latin America artists globally.
"Anything and everywhere is up for grabs."
Of course, records will continue to be broken alongside the growth of streaming services - which give users access to a vast library of on-demand music for a monthly fee.
In March, Spotify announced it had attracted 50 million subscribers. Apple Music, which is yet to reach its second birthday, has already attracted 27 million paying customers; while Google Play, Amazon Unlimited, Deezer and YouTube and dozens of others have contributed to Despacito's success.
Critics might point out that the song would never have achieved such visibility without Bieber's contribution, but Sir Lucian was candid about how Universal had harnessed the star's brand power.
"Bringing in Justin Bieber meant that we could take something that was well on its way, and really take it to heights that would have been perceived as unimaginable when the song was written," he told the BBC.
"We were at one level, and he helped us get to the next."
Fonsi also paid tribute to Bieber's contribution, and reflected on his breathtaking success in a phone interview from Lisbon.
Ed Sheeran's Twitter page reappeared on Tuesday with a spring clean of old tweets after a brief disappearance prompted speculation that the singer had quit the social media platform after the mixed reaction to his cameo on TV show "Game of Thrones."
Sheeran's Twitter account, which boasts 14 million followers, appeared to have been deactivated on Monday. On Tuesday, it was live again, but many of Sheeran's 30,000 tweets, including recent posts and comments from fans, had been deleted.
A representative for the British singer did not immediately respond to requests for comment.
Sheeran was active on Instagram on Tuesday, posting a photo of a cat and a picture from the set of "Game of Thrones." On Sunday he also posted photos and a video of his “Game of Thrones” cameo.
Sheeran's scene on Sunday's HBO medieval fantasy series, in which he plays a singing soldier who encounters character Arya Stark, garnered mixed reception from avid "Game of Thrones" fans. Many criticised his cameo as distracting in a show that does not usually use celebrities.
The 26-year-old singer, whose latest album, "Divide," topped charts in the United States and Britain earlier this year, has been vocal about his dislike of Twitter.
He told Britain's Sun newspaper earlier this month that it was "nothing but people saying mean things" and that he had stopped using the platform regularly.
R&B singer R Kelly has denied allegations that he is holding several young women in an "abusive cult".
The singer's lawyer said he would work "diligently and forcibly to pursue his accusers and clear his name".
A Buzzfeed report accuses the singer of brainwashing women, who got closer to him in an effort to boost their musical careers.
Kelly has faced previous accusations of sexual misconduct, but was never found guilty. He denies any wrongdoing.
The report, which quoted three unnamed sets of parents, said they had not seen or spoken with their daughters for months, and that the women, all of them over the age of consent, had their routines controlled by the singer.
That included rules about what they could eat and wear, when to bath and sleep and how to engage in sexual encounters recorded by him, they said.
Three former members of Kelly's inner circle were also interviewed, saying that six women lived in properties managed by the singer in similar conditions.
If they broke the "rules", they said, the women could be punished physically and verbally by the singer, according to to report.
Some of the parents reported their concerns to the police, but the women said they were not being held against their will.
The singer's lawyer, Linda Mensch, said in a statement: "Robert Kelly is both alarmed and disturbed at the recent revelations attributed to him. Mr Kelly unequivocally denies such allegations."
BuzzFeed has said it is standing by its reporting.
In 2008, R Kelly was acquitted of 14 charges of making child pornography after a videotape emerged allegedly showing him having sex with a 14-year-old girl.
Kelly is one of the most successful R&B artists of all time, with 40 million records sold worldwide. His best known his include I Believe I Can Fly and Ignition (Remix).
