Kristin Cavallari has a new man in her life.
The “Hills” star debuted her boyfriend, Mark Estes, in an Instagram selfie in February 2024, revealing he “makes [her] happy.”
The hunky influencer also took to social media to share a PDA-packed TikTok video of himself and Cavallari on vacation in Mexico.
Here’s everything to know about Estes.

He is 12 years her junior
Fans were quick to notice the two-digit age gap between the pair.
Cavallari was born in January 1987, while her new man arrived in October 1999.
However, Pvnew exclusively reported that the duo were “unfazed” by the criticism.
“They’re two consenting adults who like each other, so who cares?” a source close to Estes told us.
“Everyone is entitled to their opinion, but Kristin and Mark aren’t paying attention to the noise.”
Estes is a popular TikToker
Estes is part of a TikTok group called the Montana Boyz.
The trio regularly post thirst traps of themselves lip-syncing to the camera while rocking cowboy hats.
Estes, who is often shirtless in the group’s videos, boasts more than 400,000 views on his personal TikTok page.
The Montana Boyz account, meanwhile, has more than 9 million views.
He was a college athlete
Estes graduated from Montana Technological University, where he was a football player, in December 2023 with a bachelor’s degree in interdisciplinary arts and sciences.
The athlete was a wide receiver for the school’s Orediggers team and scored five touchdowns in 2021 alone, according to his bio.
Their romance got hot and heavy quickly
Though Pvnew reported in February 2024 that Cavallari and Estes’ romance was “new” and not “official yet,” it seems things got hot and heavy very quickly.
“Kristin thinks Mark is super hot. He’s very flirtatious, and she’s loving it,” a source told us, noting that the pair only started talking a few weeks before posting each other on social media.
In fact, Estes publicly described himself as “single” on Valentine’s Day, just two weeks before posting a loved-up TikTok video with the “Laguna Beach” star.
They both spend time in Tennessee
According to his Instagram bio, the Montana native, who has a brother named Cade, now divides his time between his home state and Nashville.
Cavallari, for her part, resides in nearby Franklin, Tenn., with her three children, Camden, Jaxon and Saylor, whom she shares with her ex-husband, Jay Cutler.
