Kris Jenner’s boyfriend and Kardashian bodyguard, Corey Gamble was on the witness stand on Tuesday (April 26) where he testified to hearing Blac Chyna threaten to kill Rob Kardashian multiple times. Gamble says he heard Chyna threaten Rob over the phone and in person. Corey says he was awoken by a phone call from Rob to Kris and through the speakerphone, he could hear Chyna screaming, "F*** you, I'm a kill you fat mother f*****." Corey rushed to Kylie Jenner’s home where Rob and Chyna were staying to diffuse the situation. Once at the front door, which was open, Corey says he heard Chyna threaten Rob again, telling him she would “kill him.” Once inside he saw Chyna with a “large rod,” which she dropped at the sight of Gamble. Corey says he tried getting Rob out of the house and Chyna smelled of alcohol. Corey says Chyna was furious, she chased Rob and jumped in the back of the car as Rob was leaving, and hit him several times in the back of the head. Chyna threw a chair at Rob’s car, then tried to throw a table at it before Gamble stopped her. Chyna denies she threw anything or said she was going to kill Rob.
