Rob Kardashian brands Blac Chyna a ‘psycho b***h’ as he shows off scratches on his arm in Snapchat clip
Reality star implied his fiancee scratched him just days before split rumours emerged
ROB Kardashian shared a disturbing video in which he calls his pregnant fiancee Blac Chyna a "psycho b***h" just days before split rumours emerged.
Fans have been speculating about a break-up since Rob deleted all his pictures from Instagram, and the Snapchat clip appears to show a scratch on his arm as evidence of a bust-up between the pair.
In the video, Rob films his arm as he is driving in a car with Blac, and the footage appears to show a large red scratch on his skin.
He said: "Look what she did to me. Crazy ass..."
Rob then films Blac, calling her a "psycho b***h", but the pregnant star appears to laugh the insult off by grinning and playfully swiping the camera away.
The video was uploaded to Snapchat just days before rumours of a split emerged.
Rob deleted all his images from his Instagram account, sparking reports of trouble in the relationship.

He is known for cleansing his social media accounts during stressful times, and reports suggest Rob ended the engagement after discovering suspicious messages on Blac's phone.
Neither Rob, 29, or Blac, 28, have yet commented on the split rumours.
Fans were taken by surprise when the couple started dating in January as Blac, who has a three-year-old son King Cairo with her former fiance Tyga, had been feuding with Rob's sister Kylie Jenner for some time.
Chyna was furious when Tyga, 26, started dating Kylie, 18, soon after their split but she and the Kardashian/Jenner family appeared to have put their differences behind them in recent months.
The couple are due to welcome their first child later this year.
