|Bieber walks off stage|
The singer, who found fame at 13 and went on to become a global pop phenomenon, scooped five prizes in Milan, including Best Male and Biggest Fans, and next month is to release his first album in three years, during which bad behavior offstage risked damaging his family-friendly teen heartthrob image.
"I'm done, I'm not doing the show," he told his fans, known as "beliebers", after complaining that they did not listen to him while he was trying to wipe up spilled water, a video from the concert posted on the website of Norwegian daily VG showed.
"Sadly it's been a rough week for me, long days, no sleep, while having to be 'on' as they would say for cameras fans etc...," he later said in a post on Instagram, apologizing.
"In no way did I mean to come across mean, but chose to end the show as the people in the front row would not listen."
His private jet took off from Oslo's airport just after midnight, leaving his fans shaken, and some in tears, VG said.
Bieber is extremely popular in Norway, with some schools even having rescheduled exams in the past so their students could attend his concerts.

On Wednesday, Justin Bieber got caught up in one of the most awkward interviews ever on Spanish radio. The 21-year-old went from looking confused to fed up to irritated during the nine minute exchange, before getting up and walking out.
The bizarre featured three Spanish speaking DJs - one of whom had very broken English - and no translator for Bieber, who being Canadian can parle Français, but does not habla Español.
The interview starts amicably enough, but it soon becomes apparent that the one who's supposed to be serving as the translator has a tentative grip on the English language.
