Kristin Cavallari and Mark Estes have separated

Kristin Cavallari and Mark Estes have split after seven months of dating.

The 37-year-old reality TV star and the 24-year-old Montana Boyz TikToker recently ended their brief romance, with Kristin telling podcast host Alex Cooper during their “Unwell” tour stop in Austin, Texas that the split was “fresh ” be “.

Kristin previously revealed that she first noticed Mark in September 2023 while using TikTok and that she immediately thought he was “so hot.”

On her podcast Let's Be Honest in March 2024, she said: “In September I was scrolling and I came across this boy band, I guess you could call them The Montana Boyz. So I'm like, “Holy shit, who are these guys?” Because they're so hot, especially this one I'm going to call Montana.

Then she received a message from her account saying “I love you” and invited her to her podcast, where she immediately hit it off with Mark.

Kristin said: “That attraction was always there, but when I met him I thought he was actually a really nice, good guy. He is very sweet from the start. He was so sweet to me.”

“Dating a 24-year-old wasn’t what I was looking for. This is something I never thought would ever happen. I understand what it looks like to the outside world. I really do. I understand that.” He’s not your typical 24-year-old.

“I think it's a lot of things. I think sex for women gets better with age. Because I think women, when you're in your early 20s and stuff, you're insecure in a lot of ways, you're worried about your body or what you look like. I've put all that behind me and think I'm more physically present during sex than ever before. And I'm so attracted to (Mark). And I just think we have really hot sex.”

Kristin was previously married to former NFL player Jay Cutler for seven years before they split in 2020.

She shares sons Camden and Jaxon and daughter Saylor with her former spouse.
