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

Kristin Cavallari has called it quits with her influencer boyfriend Mark Estes.

“The Hills” alum, 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.

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 breakup came weeks after Estes went on her “Let’s Be Honest” podcast to talk about his “end goals” for their romance on Sept. 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 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 hospitalized.

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