If sources are to be believed, then Khloe Kardashian is feeling "super betrayed" after Rob Kardashian has moved in with Blac Chyna.
An insider revealed that the 31-year-old TV star is livid and is not able to understand why someone in her own family would stab her, People magazine reports.
Earlier, a source had confirmed that the 28-year-old TV star and Chyna are dating and the former is now staying in her home after living with sister Khloe for years.
As per sources, the 'Keeping Up with the Kardashians' star, who has always stood by Rob's side and many times has gone out of her way to help him, is feeling very frustrated on being cheated.
