Justin Bieber's not done saying "Sorry" just yet.
A fan posted a video of the 21-year-old singer angrily storming off stage in the middle of a concert in Norway, after getting into a conflict with fans in the front row.
An eyewitness at the show tells ET that Bieber "drank from a water bottle and gave the rest to the girls nearest the stage."
"He went to dry up the water with a towel when fans tried to take the towel from Bieber," the eyewitness continues. "He became angry and walked off the stage," cutting short the concert after just one song and causing many fans to be disappointed, some to the point of tears.
Here's the video.

Bieber later apologized to his fans on Instagram, writing, "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. 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"
"Hopefully people will understand where I am coming from," the singer continued. "I don't always handle things the right way but I'm human and I'm working on getting better at responding not reacting. Unfortunately people were affected by this as am I."
"For the people in the back I am so sorry and for anyone I may have disappointed I'm sorry," Bieber concluded. "Sorry for wasting the TV people's time. I'll be sure to make it up to you next time on tour.. With love Justin."

The apology comes less than a week after Bieber released his single, "Sorry," which the singer said would be an end to his apologies.
“It’s kind of the stamp in the end of the apologies that I’m giving to people, to the media,” he told the "Smallzy’s Surgery" radio show in Austrailia, "I’m ready to just move on.”
