Blac Chyna’s defamation trial against the Kardashian family and matriarch, Kris Jenner, saw explosive testimony Thursday afternoon, according to TMZ.

Kris Jenner testified she was told Blac Chyna threatened to kill youngest daughter, Kylie Jenner, when the girl was dating rapper Tyga. Blac Chyna was Tyga's ex-fiancé. Jenner also told the court she wasn't concerned when Chyna started dating her son, Rob Kardashian.

Despite the worrying nature of the claim, Jenner said she didn’t actually recall the incident at first.  Chyna’s attorney asked Jenner if Chyna ever threatened to kill Kylie, Jenner needed the lawyer to bring out Jenner’s deposition to refresh her memory, and to point out where Jenner made the allegation.

Jenner tried to deflect the question by saying to the lawyer that she would have to ask Kylie and Tyga, as they would have had first-hand information. Jenner told the court, "I probably thought it was just some drama, which I'm used to."

Even after hearing about the supposed threat, Jenner says she still supported Rob's engagement to Blac Chyna, explaining, "I love second chances, and I wanted them to win. I wanted my son to be happy." She added she didn’t really believe that Chyna’s threat was real.

Chyna is suning  Kris, Kylie, Kim and Khloe, claiming that the Jenner-Kardashian family lied about her assaulting Rob Kardashian to E! executives to sabotage a second season of Rob & Chyna. The 2016 reality show that featured the couple as they prepared to have a baby together. Although a second season was announced, it never aired after the couple split in early 2017.
