Kristin Cavallari further detailed her estrangement from her father, Dennis Cavallari, alleging he once “traumatized” her son.

“I haven’t talked to my dad in probably three years,” the TV personality shared on the “Boyfriend Material” podcast with Harry Jowsey earlier this week.

She described cutting ties with her dad as “one of the best decisions,” saying, “I always had a rough relationship with my dad.”

Kristin, 38, continued, “He crossed the line with one of my boys and that’s a deal breaker for me, especially when he had zero accountability, no apology.”

“He traumatized my kids,” she claimed. “And I have no room for that in my life, and so that was it.”

The “Hills” alum then elaborated on how she would handle the situation if she were the parent in this situation.

“To be honest with you, as a mom, if I had a kid and I really f–ked up with my kid and they wanted to cut me out of their life, I would do everything imaginable to not let that happen,” she said.

“I would be like, ‘I am so f–king sorry.’ Showing up at your house, like, doing everything imaginable and my dad in a lot of ways was like, ‘OK.’”

Kristin alleged that her dad “hasn’t tried” to make amends.

The “Laguna Beach” alum also claimed her broken relationship with her dad wasn’t due to addiction issues but because he is allegedly a “narcissist,” who has taken “zero accountability.”

Kristin hinted that her father thinks his actions are her fault.

The “Let’s Be Honest” podcaster is mom to three kids — sons Camden, 12, Jaxon, 11, and daughter Saylor, 9 — whom she shares with ex-husband Jay Cutler. The exes was married from 2013 to 2020.

Kristin opened up about her and Dennis’ relationship during an episode of her podcast with psychologist Dr. Sherrie Campbell in December 2023.

“I actually didn’t even realize that my dad was a narcissist until I was an adult,” she admitted.

Vaguely talking about her father’s incident with her kids at the time, she added, “I can take the abuse. I have my whole life. But it’s like, when you start now messing with my kids — I’m not doing it.”

Kristin also discussed the importance of her father taking “accountability” while chatting with Page Six radio earlier this month, adding that “he’s out of [her] life forever.”
