Kristin Cavallari announced the news of her split while on stage during Alex Cooper’s 'Unwell' live tour in Austin, Texas.

The 'Call Her Daddy' podcaster was the first to reveal to a live audience that Cavallari was "newly single" during a segment dedicated to relationship advice.

According to sources, Cavallari did not delve into too many details about the breakup, simply stating that it was "fresh."

Her admission of being single surprised many, especially since the couple had recently appeared strong and united in public.

Their breakup came shortly after Estes appeared on Cavallari's 'Let’s Be Honest' podcast earlier in September, where he openly discussed the future of their relationship.

During the episode, Estes expressed his hopes of settling down and starting a family but acknowledged that he wasn’t in a rush to make any drastic decisions.

"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. I don’t think we need to make any serious decisions … right now," Estes shared on the podcast.

In September 2023, the reality star found the 24-year-old on TikTok, where he had become popular as a member of a viral group known as the 'Montana Boyz'.

Estes and his group of friends became internet sensations thanks to their cowboy-themed content, which included lip-syncing to popular songs and videos of them lounging in rural settings.

By February 2024, Cavallari and Estes were officially dating, and their relationship swiftly attracted media attention.

Despite these allegations, Estes was never formally charged, and the case did not appear to impact his budding social media career.

The couple's relationship advanced rapidly, with Cavallari publicly sharing photos of their time together.

In one memorable Instagram post, she posted a selfie with Estes from a trip to Mexico, captioning it, "He makes me happy."
