Rob accused Chyna of cheating on him multiple times and being on drugs in NSFW Instagram posts on Wednesday.
Blac Chyna seems to have cooled off.
While Rob Kardashian continues his tirade against the 29-year-old model, accusing her of cheating on him multiple times and being on drugs, Chyna has been showing off her bling.
The mother of two initially responded to Rob's heated claims on Wednesday morning with allegations of her own, accusing her ex-fiance of also cheating on her and being physically abusive in since-deleted Snapchats. Hours later, she appeared to be back to her usual routine, as she showed off her diamond watch on the app while listening to Drake's "Cameras."
While Chyna appears to have taken a break from the drama, a source tells ET that her and Rob's relationship "was always so volatile."
"They either love or hate each other -- no in between. A rocky relationship is also something Rob never needed," the source says. "He can’t mentally or emotionally handle it. This is really going to set him off."
