Justin Bieber has lashed out at 'fans' who have been trolling his rumoured new girlfriend, Sofia Richie, on Instagram.

Justin, who has been sharing shots of what looks like the best holiday ever with Sofia in Japan, has even threatened to make his IG private if so-calledfans aren't a bit nicer.

One fan posted: "I won't be celebrating all your dump actions, she's gross and your treating your fans like s**t"

While another simply commented: "Trash". No wonder JB was annoyed.

He hit back saying: "I'm gonna make my Instagram private if you guys don't stop the hate this is getting out of hand, if you guys are really fans you wouldn't be so mean to people that I like"

And he's got a point, quite honestly.

But someBeliebers weren't happy about their idol telling them off and #RIPBeliebers has been trending all day. Ouch.
