There are conflicting reports about whether “Keeping Up With the Kardashians” star Rob Kardashian is still engaged to Blac Chyna, but one thing is certain: She drew blood from the reality star before their alleged split. Kardashian posted a video to Snapchat two weeks ago after Chyna scratched him. Even though videos only lasted for 24 hours on the ephemeral app, the video was preserved through an Instagram account dedicated to Kardashian's posts.

The clip opens up with Kardashian’s tattooed arm. It appears that it has been injured. “Look what she did to me. Crazy a--,” he says in the clip.

Chyna, 28, looks annoyed as he films her in the car. But he might have just been joking around since she gives a slight smile and then swats his camera away. Before the video ends, he calls her a “psycho b----.”

Breakup rumors surfaced Monday after Kardashian, 29, scrubbed his Instagram account, removing all pictures of Chyna. Eventually, he deleted every picture on his page. Kardashian reportedly flipped after he and his fiancé got into a fight while filming their reality show, “Rob & Chyna.”

“Rob [Kardashian] and [Blac Chyna] have been getting into little tiffs and Blac Chyna flipped on Rob,” E! Online reported Tuesday. “He was so pissed at how she spoke to him, so he deleted everything about her to hurt her.”

Chyna feared the reality star cheated on her. “Rob has never cheated on her, but she is very paranoid about that from past experiences,” the source told E! Online. Despite their fight, the couple is “fine” now. “[They're] back in love and have spoken through their fight,” the person added.

Their spat was captured by cameras. “They filmed over the weekend and had an argument,” a source told People Magazine Monday, adding, “It's hard to see Rob and Chyna actually splitting. Rob is looking forward to becoming a dad. It would take a lot for him to break up with her.”
