Blac Chyna opened up about her former friendship with Kim Kardashian and how it changed after her ex-fiancé Tyga started dating Kim’s little sister Kylie Jenner.

“Me and Kim, we were really good friends. I was on her show and all this stuff like that. We lived in the same community,” Blac Chyna, 35, recalled of her 2014 cameo on Keeping Up With the Kardashians during the Thursday, October 26 episode of the “Viall Files.” “And then her little sister started talking to Tyga, which was really crazy because she was underage and then everybody came at me and started attacking me.”

She added, “Nobody’s seen the betrayal that was going on behind my back of me talking to somebody — Kim — and then her little sister, who she has no control over, started talking to my fiancé and then I get attacked.”

Blac Chyna — whose real name is Angela White — began dating Tyga, 33, in 2011 after meeting on the set of his “Rack City” music video. The pair welcomed their son, King Cairo, in 2012 before announcing their engagement in 2014. However, they split later that year after Tyga sparked dating rumors with the Kylie Cosmetics founder, 26.

“I feel like it ran its course and then he started talking to Kylie at the time, which she was like 16 or something,” she told host Nick Viall. “Yeah, I was engaged and stuff, so that’s kind of what ended it.”
