On Wednesday, Kardashian, 30, took to Instagram to blast his ex Chyna, 29, in a series of extremely graphic and expletive-ridden posts, some of which have since been taken down. Chyna responded to the onslaught of messages in a since-deleted Snapchat post, alleging that Kardashian hit her. (Neither Kardashian nor Chyna immediately responded to PEOPLE’s request for comment.)
“Hahahaha Chyna just sent me this video saying happy 4th of July what a crazy person,” he captioned a video of Chyna kissing a man in bed. “Come spend time with your daughter instead of f—ing me and then this dude right after. U need help.”
In another post, Kardashian shared a screenshot of an alleged text conversation between himself and “the dude Chyna got caught cheating on me with.”
“This is the dude Chyna got caught cheating on me with for a minute now. And look he texted me asking for help and said he needed money cuz he can’t afford to pay Chyna’s bill so that’s why I pay her bills,” he wrote. “More receipts are coming. Just yesterday Chyna sent me her p— and everything and said she gonna come f— me … wait for it. 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 f—ing including me.”
In another highly graphic post, Kardashian shared a screenshot of an alleged text conversation between himself and Chyna, which included an alleged photo of Chyna’s exposed genital area.
“This is from Chyna yesterday to me,” he wrote. “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.”
Kardashian then shared a photo of the man allegedly at the center of the drama. (He did not immediately respond to PEOPLE’s request for comment.)
“And this the dude that posted a pic in the same bed Chyna and I made our baby in,” he wrote. “The house that I pay for. That robe i prob paid for. Imma send u messages from this dude asking to link with me or he gonna expose Chyna if I don’t help him get money cuz he can’t handle the bills to take care of Chyna. Lol. I pay lambo. Ferrari. Down payment on the rolls. Downpayment on your moms car. I pay your mother since u won’t even call your own mother back in months.”
“I prob spent a million alone in the past 2 months. 90K necklaces. 70K watch. The Ferrari that u pretend u got yourself,” he continued. “Chyna I hope U find help and to this corn ball, u thirsty as f— for hitting me and begging to link with me and if I don’t help u get money then u gonna expose Chyna. Bro go back to your son who is at home instead u out here f—ing someone that everyone f—s including me. Lol. Clown. She everybody’s and it’s been that way. The disrespect in the bed that my baby daughter lays in. Chyna u literally lost on this one.”
Kardashian went on to share several more extremely explicit posts, alleging that Chyna uses drugs. He also posted two more alleged naked photos of her, both of which have since been taken down.
“Everyone wonders how Chyna lost all that weight after the baby and she lies to everyone but no I’m such a great Husband that on our anniversary I paid 100K to do this surgery to get all everything fixed as much as they could,” he wrote in another post. “And then guess what she did after she was all healed when I was by her side the entire time. She left me and my baby which she had out of spite to get back at her other baby daddy. I can’t believe u would disrespect me like this.”
In another post, Kardashian said: “I’m a savage and I always have been and I always will be and I don’t give a f—.”
“Thank u God and my Dad for watching down on me and showing me this,” he wrote. “Damn I spent millions on this girl in less than a year and a half and she f—ing dudes who hit me [up] begging for money or they gonna expose her. Too late man.”
“I’m making a lemonade album for sure this year,” he added in another post.
Chyna responded to Kardashian’s posts on Snapchat, alleging that he hit her.
“On my kids but I’m supposed to be quiet because you’re a Kardashian,” she wrote in a Snapchat post which has since been deleted. “The light will come to the light.”
Chyna’s rep did not immediately comment, but a source close to the reality star said that she is the victim in this situation: “She’s had to have a new phone number every month and constantly has to change her number. While everyone is writing stories and thinking it’s fun gossip, it’s actually dangerous.”
Kardashian and Chyna’s roller coaster relationship began in January 2016, when the two went public with their romance. The pairing initially raised eyebrows due to Chyna’s complicated history with the Kardashian-Jenner family: Chyna shares a son with Kardashian’s sister Kylie Jenner‘s former boyfriend Tyga, and is also best friends with Amber Rose, an ex of Kanye West, who is now married to Rob’s sister Kim Kardashian West.
Kardashian proposed to Chyna in April 2016, and a month later, they announced they were expecting their first child. The two welcomed their daughter, Dream Renée, last November. PEOPLE confirmed the two had called off their engagement in February, and in the months since, the status of their relationship has remained unclear, though the two appeared to have been on relatively good terms.
