Rob Kardashian calls out Blac Chyna for 'cheating': 'U need help'

July 5 (UPI) -- Rob Kardashian accused ex-fiancée Blac Chyna of cheating in a series of posts Wednesday on Instagram.

The 30-year-old reality star shared explicit photos of Blac Chyna on the social media site after claiming the 29-year-old model slept with multiple men while they were together.

"Never once have I cheated on Chyna and I remained loyal to her even after all the cheating she been doing and the multiple men she been [expletive]," he captioned a screenshot of a text conversation with one of Blac Chyna's alleged lovers.

Kardashian posted a video Blac Chyna sent him of her kissing another man in bed. He later said the model sexually propositioned him the same day the clip was filmed.

"I never been so disrespected in my life," he added to a screenshot of an explicit exchange he had with Blac Chyna on Tuesday. "I just bought her 250K of jewelry yesterday. This woman is so disrespectful and I don't care."

Kardashian followed up by claiming he paid for Blac Chyna to have $100,000 worth of plastic surgery after their daughter, Dream, was born in November.

"I had my daughter out of Love but this woman left the second I paid for her body surgery and then she was out. Chyna please get help," he wrote.

Blac Chyna has yet to address the cheating rumors, but claimed Kardashian was abusive in a since-deleted post Tuesday on Snapchat.

"Rob u did all this but u beat me up and try act like 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," she wrote.
