For the second time in a week, Justin Bieber stormed off stage and ended a gig early, this time in Oslo, Norway during a show that was being taped for television. One song into the gig, Bieber took a moment to try to mop up a spill at the front of the stage, but when audience members there wouldn't listen to him, he turned abruptly, whipped off his headset and left the stage,  saying, "Never mind. I'm done, I'm not doing the show." The crowd, obviously, was a bit confused. This is great, just great.

What's also great? His apology on Instagram. Bieber — or, obviously, someone who works for Bieber — posted a lengthy mea culpa, and it's always entertaining when the pop star clearly doesn't write something himself. You can tell because the grammar is pretty decent and it usually includes a little passive-aggressive Bieber-bashing.

"Sadly it's been a rough week for me — long days, no sleep while having to be 'on,' as they would say, for cameras and fans," the post reads. "I don't always handle things the right way but I'm human and I'm working on getting better at responding not reacting." There's a whole lot going on in there.
