The 28-year-old model, who is engaged to and expecting with Jenner's half-brother Rob Kardashian, confirmed she and the 19-year-old reality star are in a "positive" place despite their previous tensions over Tyga.
"We've all talked, I've met up with Kylie," the bride-to-be said in the Sept. 12 issue of People. "Everybody is mature. We're not holding onto grudges. We've moved on."
Blac Chyna shares a 3-year-old son with Tyga, who is dating Jenner. She previously clashed with the Kardashians after her friend Amber Rose criticized Jenner and Tyga's relationship, and over comments she made about the teenager's cooking show.
"Every family is going to be defensive in the beginning; I don't care who you are or what the situation is -- they're going to be protective," the model said. "But everything is positive now."
"[There's] no animosity [and] everybody is super comfortable," she added. "I feel comfortable with Kylie being around my son, King, and I'm sure Tyga feels comfortable having King around Rob."
Blac Chyna and Jenner previously dismissed rumors of a feud by sharing photos together in April. The model recently claimed in the October issue of Elle that she wasn't fazed when Jenner and Tyga started dating.
"When you don't want to be in a relationship with somebody anymore, you don't give a [expletive] what they're doing," she said. "I was just like, 'Thank God I'm out of that situation.' And honestly, it was the best thing that I could've done, because my life has changed so much for the better."
Blac Chyna and Kardashian will give fans a glimpse into their relationship on the new E! series Rob & Chyna. Jenner made headlines this week for giving Tyga a $300,000 Bentley after his Ferrari was reportedly repossessed.
