Mark Estes

Estes dated Kristin Cavallari from 2024 until their split after seven months. They became Instagram official in February 2024 after meeting through social media, when Estes accidentally sent Cavallari a direct message from the Montana Boyz account. Cavallari later confirmed that they ended the relationship because she felt it was not right for the long term.

Estes met Cavallari's children, Camden, Jaxon and Saylor, on the night of his first date with their mother. He later spent time with Camden and Jaxon at Cavallari's Nashville home. Estes and influencer Sommer Ray made their relationship public in June 2025.

Estes played wide receiver for Montana State University and Montana Tech. At Montana State, he wore number 82 and appeared in all 15 games during the 2019 season, emerging as a threat in both the passing and running games late in the year. He finished that season with six carries for 64 yards and three catches for 29 yards, and he redshirted in 2018.

He concluded his college football career with Montana Tech in November 2023 after six seasons, including one redshirt season. Before college, he was an all-state football selection at Drummond in 2015 and a second-team all-state selection at Glacier High School in 2017. He also won a state track and field championship.

Estes is a member of Montana Boyz, a TikTok collective that posts videos centered on cowboy life in Montana. The group includes Kade Wilcox and Kaleb Winterburn, who publicly supported Estes during his relationship with Cavallari. Estes also maintains his own TikTok account.

His social media profile helped bring him to Cavallari's attention before they met in person. He later appeared with her in a fragrance campaign for Uncommon James and in videos shared on TikTok and Instagram.
