Justin Bieber is not okay with all the hate Sofia Richie is getting on social media.

Bieber — who is currently in Tokyo with Richie — took to Instagram on Sunday, Aug. 14, to address his fans’ unkind words towards his rumored girlfriend. The 22-year-old “Sorry” crooner even threatened to make his Instagram account private if the pour of negative comments geared towards the 17-year-old model continues.

“I'm gonna make my Instagram private if you guys don't stop the hate,” Bieber captioned a black and white photo of the pair in which Richie is seen holding finger guns up to the singer’s head.

“This is getting out of hand," he continued. “If you guys are really fans you wouldn't be so mean to people that I like.”

Richie, who is the daughter of music icon Lionel Richie and sister of socialite Nicole Richie, first made an appearance on the pop star’s Instagram on Friday. Richie has also posted some photos of the singer on her own Instagram page. However, her Instagram account was flooded with comments of hate and snake emojis since she was linked to the Canadian pop star.

“You really f--king suck. You barely know justin and he’s all about you. We’ve been here for 8 yrs & he’s putting US down for your irrelevant hoe ass,” one user commented.

“Jelena forever,” another user wrote, referring to Bieber’s ex-girlfriend Selena Gomez.

Although Bieber and Richie’s Tokyo trip has fuelled romance rumors, multiple sources told E! News that the two are "just friends" and "nothing serious" is going on between them.

The pair was most recently photographed holding hands in Tokyo, where Bieber has two Purpose World Tour shows over the weekend, People reported.

Prior to jetting to Japan, Bieber was spotted earlier this month skinny-dipping in Hawaii with Sahara Ray.
