Mark Estes is the new man in Kristin Cavallari‘s life. The Laguna Beach star, 37, made her new relationship official on Instagram on February 27, with a smiley picture of the couple in Mexico, and the caption, “He makes me happy.” Mark, 24, also posted Kristin for the first time on his TikTok, where he has a huge following. In the video, the pair kissed and hugged in their bathing suits on their tropical vacation.

Kristin, who divorced Jay Cutler three years ago, seems happier than ever with her new beau. But who is Mark Estes? Get to know the handsome TikToker below.

Mark is a TikTok star.

Mark is known for being a part of the Montana Boyz, a TikTok collective with nearly 460,000 followers. The group also includes Kaleb Campbell Winterburn and Kade Cutter Wilcox. They typically share dancing videos and show off their cowboy lifestyles in their videos. The three boys also tend to take their shirts off pretty often in their TikToks.

He lives in Nashville

Mark is based in Nashville — as is Kristin! It’s unclear how they met, but it was likely because of living in the same city. Kristin resides in Nashville with her three children that she shares with her ex-husband.

He’s from Montana.

Mark was born and raised in Montana, hence why he’s one of the “Montana Boyz.” He attended Glacier High School in Kalispell, Montana.

He played college football.

Mark played football for both Montana State University and Montana Tech University as a wide receiver. He finished his football career at the latter school in November 2023. “What a ride,” Mark wrote on Instagram. “Thankful for the last 6 years of what this sport has brought me. Thanks to all the coaches and brothers I met along the way ❤️.”

He has a clothing line.

Mark’s clothing line is called Belmont Acres. He created it with the other two “Montana Boyz.” The company’s website says Belmont Acres “was born from a shared vision” of Mark, Kaleb, and Kade “who all embraced and cultivated the outdoors from a young age, experiencing firsthand the challenges and triumphs that define life under the Big Sky.”
