Rob Kardashian has posted several nude photographs of his on-off girlfriend Blac Chyna on Instagram and accused her of cheating on him with eight men in less than a month.

The bitter online rant sparked a furious response from Chyna who accused Rob of beating her.

Their feud began when Rob posted  an image of his on-again off-again girlfriend wearing no underwear on Instagram Wednesday morning.

He claims Chyna sent him the picture on July 4 before sleeping with another man.

‘This is from Chyna yesterday to me. I never been so disrespected in my life. I just bought her 250K of jewelry yesterday. This woman is so disrespectful and I don’t care,’ he wrote.

Chyna responded to the allegations on Snapchat, claiming in a now-deleted post that Rob physically abused her.

‘Rob u did all this but u beat me up and try act it never happen !!!!! U put hand on me I swear on god !!!!! On my kids but I’m supposed to be quiet because you’re a Kardashian (sic),’ she wrote in the post that has since been deleted.

She also posted of her showing off a diamond-encrusted watch and bracelets – presumably some of the expensive jewelry Rob claimed to have purchased for her.

Rob started his Instagram rant by sharing a video clip of Chyna kissing another man.  Chyna is seen on top of the man while kissing him and gazing into the camera.

‘Hahahaha Chyna just sent me this video saying happy 4th of July what a crazy person. Come spend time with your daughter instead of f***ing me and then this dude right after. U need help’ Rob wrote next to the intimate clip.

Rob could find himself in legal trouble as revenge porn laws are in effect in the state of California, where it is considered a misdemeanor punishable by up to six months in jail and a $1,000 fine.

At first, Rob said that the man kissing Chyna in the clip was a rapper named Rarri True. But Instagram users pointed out to the reality star that the man in the video is actually a musician named Mechie. Rarri True is a Chicago-born rapper. Mechie, 24, from Washington, DC, is described as an R&B singer.

Rob later amended his post, but stood by his claims that Chyna also slept with Rarri True.

Instagram deleted his account, after which he moved to Twitter to continue his rants.
