Justin Bieber has hit back at fans on Instagram, for leaving mean comments about his rumoured girlfriend Sofia Ritchie. While Justin and Sofia haven't confirmed their relationship, they’ve both shared pics of themselves hanging out together and incurred the wrath of his Beliebers.

On Saturday Justin shared a series of black and white snaps of him and Sofia sitting in a car. While none of the pics were captioned, some fans commented that the 17-year-old was “ugly” while others simply wrote “my man”.

But after some of the nasty comments, Justin hit back. “I'm gonna make my Instagram private if you guys don't stop the hate this is getting out of hand,” he wrote. “If you guys are really fans you wouldn't be so mean to people that I like.”

Some then accused Justin of turning his back on his ‘Beliebers’, saying he’d chosen Sofia over his fans. Sofia had also uploaded pictures of herself and Justin, but she has now made it so no one can comment on her Instagram account.

Sofia is the daughter of singer Lionel Richie and his ex-wife Diana and is also the half-sister of his adopted daughter Nicole Ritchie. Her and Justin have been spotted spending plenty of time together over the past few days and earlier this week she joined him in Japan, as part of his Purpose world tour.
