It's more than a week since Blac Chyna's daily trial began, and there is more information being unfolded as revealed by members of the Kardashian-Jenner family. More recently, Kylie Jenner took the witness stand to share a shocking revelation.

According to Yahoo!, the beauty mogul told an LA jury on Monday that she and her ex-boyfriend, Tyga, warned Rob Kardashian about the model's history of violence and substance abuse.

However, Rob did not listen and continued his relationship with Chyna despite their stern warning.

Kylie also mentioned that her ex showed her a scar that he claimed was caused by the music video model attacking him with a knife.

Based on what the beauty mogul heard from the rapper, Kylie said she was "a little concerned."

The Kylie Cosmetics CEO said it was her "duty to express what" she knew.

Recalling the place where she met up with her brother, Kylie said she couldn't remember it, but she believed that Chyna was already pregnant with their baby.

Kylie Jenner's ex-boyfriend, Tyga, had a relationship with Blac Chyna in the past. They had a kid together named King Cairo Stevenson.

The beauty mogul's statement comes a few days after Kris Jenner claimed she was traumatized when Blac Chyna allegedly tried "to put a gun" to Rob's head.

"My daughter, 60 days prior, was put in a tub, robbed at gunpoint ... I was traumatized by this. My daughter was almost killed," the Kardashian matriarch said, explaining that she was still shocked about Kim's Paris robbery.

Another piece of information unfolded during Friday's hearing as Kris claimed that the former couple was under the influence during their fight, saying it's an "ongoing theme" in their relationship.

The entrepreneur was questioned by Chyna's lawyer, asking her about the message she previously sent to the show's showrunner.

The message reads, "She beat the s*** out of Rob's face."

She later defended herself, saying she sent it because she was upset about the altercation.

The music video model filed a $100 million lawsuit against the Kardashian-Jenner family, claiming that the famous women Kris, Kim, Khloe, and Kylie cost her tens of millions in future income.

Chyna alleged that the billionaire family told lies to the executives of E! Network that convinced them to cancel her show, "Rob & Chyna."
