Kristin Cavallari is breaking up with Mark Estes after seven months

Kristin Cavallari And Mark Estes are no longer there after 7 months of dating, TMZ has confirmed.

Sources familiar with the situation tell TMZ … Kristin broke up with Mark because their relationship had run its course and was never meant to last forever.

On Friday, Kristin briefly mentioned the breakup to the podcaster Alex Cooper while chatting onstage during one of Cooper's “Unwell Tour” stops in Austin, Texas.

You may remember… Kristin and Mark first got together in February 2024 – and Kristin made it Instagram official.

The reality star/fashion designer posted a selfie with Mark and wrote in the caption that he made her happy.

From that point on, the two were hot and heavy and seemed like a serious couple, but our sources said they never got to the stage where they would move in together full-time.

In early September, Kristin said while she was having great sex with Mark, the two were doing it I'm not talking about having children or get married.

But Mark – a co-host of the popular TikTok show Montana Boyz – previously told Kristin on her Let's Be Honest podcast that his goal was to tie the knot one day have children.
