Kristin Cavallari broke up 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 on Friday that she and Estes had split as she took the stage for Alex Cooper’s live show “Unwell” in Austin, Texas.

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

The reality TV star reportedly didn’t reveal much about their split, only saying it was “fresh.”

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

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

Cavallari already has 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 couple began dating in February 2024.

Estes is part of a social media group of three friends called the “Montana Boyz” that went viral with their cowboy content, which includes lip-syncing popular songs and relaxing in the country.

In February 2021, Estes was charged with assault after he allegedly beat up a group of students off campus while attending 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 initial criticism, Cavallari didn’t shy away from posting a selfie of them in Mexico with the caption, “He makes me happy.” Two months ago, the reality TV star also shared photos from what appeared to be a romantic trip to the Greek islands.

The couple even admitted in an episode of their podcast a few weeks ago that they had the “best sex” they’ve ever had in a relationship.
