What Went Wrong? Inside Kristin Cavallari and Mark Estes' Shocking Split After 7 Months

Kristin Cavallari is back on the market!

On Friday, September 27, the Laguna Beach alum, 37, confirmed that she and influencer boyfriend Mark Estes, 24, have called it quits.

While speaking onstage at Alex Cooper’s “Unwell” tour live show in Austin, Tex., the former reality TV star told the live audience she’s “newly single” after dating Estes for seven months.

During their chat about relationships, the blonde beauty shared that the split from the former football player was “fresh.”

The news came after Estes spoke on the "Let's Be Honest" podcast on September 3 about his "end goals" for their relationship. The social media star gushed about how he wanted to "be married" and have a baby — though he admitted he didn't want to go 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,” the Montana Boyz member said. “I don’t think we need to make any serious decisions … right now.”

Cavallari is already a mother of three, as she shares sons Camden, 12, Jaxon, 10, and daughter Saylor, 8, with ex-husband Jay Cutler.

Elsewhere on the podcast episode, Cavallari claimed that she’s having the "best s--" of her life with Estes.

The Hills star played a flirty game of "Truth or Drink" alongside Estes.

Cavallari explained how intercourse has improved for her with age, saying, "I think it’s a lot of things. I think s-- for women just gets better as you get older.”

"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 shared.

"I’ve let all of that go and I think I am more present physically during s-- than I’ve ever been. And I’m so wildly attracted to you. And I just think we have really hot s--," she said about Estes.

Estes shared a similar opinion, noting intimacy with Cavallari has been the "best s--" he's ever had "for sure."

Cavallari seemed surprised by Estes' confession as she replied, "I actually didn't know that."

"You've never said that to me. We’ve talked about how great our s-- is, but you’ve never, like, point-blank said, 'You’re the best.' I would have remembered that one," she added.

Though the couple’s romance has come to an end, they originally went public with their love in February 2024. They debut their relationship by sharing photos and video from their Valentine's Day trip to Mexico.
