During an Instagram Live that was recorded on April 8, Chase read out messages to her friends that were sent from Thompson, according to the 23-year-old. She appeared to have forgotten the girls were recording when she claimed Thompson asked her to send him private photos during the IG Live.
"Oh yeah, this is on Live. I’m about to f**k myself in the ass," she said. "Oh well, it’s fine. Might as well, at this point, it’s life. I ain’t sign nothing, you did what you did that’s on you. Tristan banged me. I did not bang him."
She went on to allege that Thompson told her she looked like his first baby mama, Jordan Craig, with whom he shares 4-year-old son Prince — noting that Kardashian isn't the usual woman he goes for.
"He wanted the status and be able to keep that status but I looked just like his ex and am his type [like] his baby mama…But he just called me and told me, ‘You’re what I like’ and I’m like, ‘You’re with someone,'” Chase continued, before insisting "there's no way" his second baby mama, Kardashian, doesn't know what's going on.
According to the outlet, the Instagram Live was filmed on the same day Chase recorded an interview for Adam22's "No Jumper Podcast," where she first alleged that Thompson, 30, cheated on the reality star, 36 — the two reconciled over the summer and share daughter True, 3.
During the interview, posted April 22, Chase and her friends — who call themselves The Blackout Girls — drank as one of her pals asked, “How was Tristan Thompson’s d**k?” to which Chase replied: "It was a peek-a-boo d**k but baby it was good.”
The brunette beauty first revealed their supposed affair began in January after Thompson allegedly claimed he was no longer with Kardashian. We “talked … hung out multiple times … went out together, everything," she claimed at the time. However, once she found out the Boston Celtics player "was not single," Chase apparently "cut it off" with him immediately.
Since making the shocking cheating allegations against the athlete, Chase revealed on TikTok on Tuesday, April 27, that Thompson has reached out to her twice since finding out about her interview.
According to Chase, Thompson contacted her as recently as two weeks ago — one day after True's birthday party.
In the TikTok clip, Chase also clarified the two actually started hanging out back in November, reiterating that she "ended things" when finding out Thompson was still in a relationship.
Despite Chase warning the athlete about the interview before it went public earlier this month, Thompson "did not tell Khloé" about the situation, an insider claimed.
"Tristan contacted Sydney about two weeks ago to try to do damage control and kept it from Khloé because he didn't seem to think it would get out," the source dished. They added that Khloé ended up finding out about her on-again-off-again boyfriend being unfaithful "with the rest of the world when the media began posting it."
"She was blindsided," the source alleged. “She has no idea what she's going to do now. She's still deciding which side of the story to believe."
And while the Good American co-founder may have not seen Thompson's most recent scandal coming, he has a history of being unfaithful to the mother-of-one.
In 2018, Thompson famously cheated with another Instagram model, Lani Blair, just days before Kardashian was due to give birth to their daughter. And only one year later, he found himself caught up in another cheating scandal when it was revealed he kissed Kylie Jenner's ex BFFL, Jordyn Woods, at a party.
