Justin Bieber is in Japan with Sofia Richie, and not only are there rumors that the two are dating, but Beliebers have been dishing out nasty comments about the 17-year-old starlet -- and the pop star has had enough.

Biebs posted a bunch of photos of Sofia, and after that he added another one. “I’m gonna make my Instagram private if you guys don’t stop the hate this is getting out of hand,” Bieber captioned the photo above. “If you guys are really fans you wouldn’t be so mean to people that I like.” Ooooh, burn!

Though Bieber was photographed naked with a bunch of models in Hawaii last month, he's been with Richie a lot lately, and if the two are on a trip together, we kinda have to assume that they're, well, *together*. So, Jelena no more -- but how long will this romance last?
