TV star Kristin Cavallari, 37, and influencer boyfriend Mark Estes, 24, split after 7 months

A TV star, 37, has called it quits with her much younger influencer boyfriend, 24, just weeks after opening up about their sex life.

Kristin Cavallari has called it quits with her much younger influencer boyfriend Mark Estes just weeks after opening up about their racy sex life.

The Hills star, 37, is back on the market seven months after debuting her romance with the 24-year-old influencer, People reported.

Cavallari confirmed Friday that she and Estes broke up as she took the stage for Alex Cooper’s Unwell tour live show in Austin, Texas.

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

The Call Her Daddy podcaster revealed to a live audience that Cavallari was “newly single” during a segment about relationship advice.

The reality television star reportedly didn’t share much about their split, only saying it’s “fresh.”

Their break-up came weeks after Estes went on her Let’s Be Honest podcast to talk about his “end goals” for their romance on September 3. During the taping, he admitted he wanted to “be married” and have a baby but didn’t want to move too fast.

“Obviously I would like to have my own kid at the end of the day, but I think we decided to just keep on keeping on,” Estes said. “I don’t think we need to make any serious decisions … right now.”

Cavallari already shares sons Camden, 12, Jaxon, 10 and Saylor, 8, with her ex-husband, former NFL quarterback Jay Cutler.

The couple recently holidayed in the Greek Islands.

They were both very affectionate on social media.

The 37-year-old mother of three discovered the 24-year-old Montana Boyz TikToker on social media in September 2023 and the pair started dating in February 2024.

Estes is part of a social media group of three friends called the Montana Boyz who went viral for their cowboy-themed content that includes lip-syncing popular songs and relaxing in the countryside.

In February 2021, Estes was accused of felony assault after he allegedly beat up a group of students off-campus while he attended Montana State University. A spokesperson for the Gallatin County Sheriff’s Office told Page Six that one of the alleged victims was hospitalised.

However, Estes was never charged.

Despite the criticism early on, Cavallari didn’t hold back from posting a selfie of them in Mexico with the caption “He makes me happy.”

Two months ago, the reality television star also shared photos of what appeared to be a romantic trip to the Greek Islands.

The split came weeks after Cavallari said they were having the “best sex” they’ve ever had in a relationship.

The couple even admitted to having the “best sex” they’ve ever had in a relationship during an episode on her podcast just weeks ago.

Estes joined Cavallari for a game of “Truth or Drink”, during which they dished on their satisfying chemistry in the bedroom as she explained how sex has gotten better for her with age.

“I think it’s a lot of things. I think sex for women just gets better as you get older,” she said.

“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.”

She added, “I’ve let all of that go and I think I am more present physically during sex than I’ve ever been. And I’m so wildly attracted to you. And I just think we have really hot sex.”

Estes surprised the former Laguna Beach star by revealing that she’s also the “best sex” he’s ever had “for sure.”
