Los Angeles - Justin Bieber stormed off stage during a TV appearance on Thursday.

The 21-year-old singer was preparing to start his performance on the Norwegian show when a fan on the front row spilled something on stage.

Justin tried to mop up the liquid, but the crowd blocked him from doing so and failed to listen to his pleas for them to stand back - so he walked off stage and declared he wouldn't do the show.

Watch his meltdown here:

The Sorry hitmaker - who also walked out of a radio interview in Spain on Wednesday - later blamed his response on having a "rough week" of long days and being underslept and promised to "work on" getting better at reacting calmly to things.

Watch him casually leave here:

He posted on Instagram: "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.

"I don't always handle things the right way but I'm human and I'm working on getting better at responding not reacting. "

Justin also apologised for his antics.

He added: "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 im sorry.
''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.(sic)"
