Kylie Jenner said in court that Blac Chyna threatened her via text message while she dated Tyga: 'She sent me a bunch of devil emojis'

• Kylie Jenner testified in court on Monday that Blac Chyna threatened her via text message.

• Jenner said Chyna sent "devil emojis" meant to convey the threat.

Kylie Jenner said in court on Monday that Blac Chyna threatened her via text message, according to the Associated Press.

Chyna, whose birth name is Angela White, is suing the Kardashian family for allegedly forcing E! to cancel "Rob and Chyna," her reality show with her ex, Rob Kardashian. The series, which premiered in 2016, aired for one season. Insider previously reported that the Kardashian family has denied Chyna's claims, saying in court that a restraining order Chyna filed against Rob halted any plans for a second season.

"From what I remember she sent me a bunch of devil emojis and said something like 'counting down the days' until she could beat me or something," said Jenner, later explaining why she did not contact the authorities about these messages at the time.

"I didn't report it, because I assumed they were empty threats," Jenner, who was a teenager at the time, continued.

Jenner, now 24, said on the stand Monday that she thought Chyna was upset about her relationship with Chyna's former partner, Tyga. Tyga, whose birth name is Michael Ray Stevenson, began dating Chyna in 2011 and split in 2014, according to Billboard. The two share a son named King Cairo Stevenson. Jenner and Tyga were later rumored to be dating in 2014 when the reality star was 17 and the rapper was 24, Billboard added.

"I felt like me dating the father of her child had something to do with it, and maybe she was out with my brother for other reasons," she said on the stand Monday.

Jenner also said she tried to warn her brother Rob about Chyna

Jenner said on the stand Monday that she tried to warn Rob of Chyna's possible ulterior movies and "felt it was my duty to express my concerns, but ultimately it was up to him."

She added that she was happy about their 2016 engagement and subsequent pregnancy, but remained skeptical.

"I was happy for my brother at the time," she said, "but just curious how it would go."

Jenner previously testified that Tyga told him Chyna slashed him with a knife during an argument while they were together. She also said in court that her brother looked upset after Chyna wrapped a phone cord around his neck in 2016. Earlier in the trial, Chyna said that she was "just being silly" while celebrating the greenlighting of "Rob & Chyna" season two.

Jenner, who returns to the stand Tuesday, said that Rob "used the words, 'She was trying to kill me.'"
