Kristin Cavallari has a new — much younger — man in her life.
The “Laguna Beach” alum, 37, debuted her romance with 24-year-old model Mark Estes in a Tuesday Instagram post.
“He makes me happy,” she captioned a photo of the pair posing for a selfie in Los Cabos, Mexico.
Estes, for his part, later shared a PDA-packed TikTok video that sees the lovebirds embracing each other in front of a pool. At one point the clip, set to the tune of Gloriana’s 2012 hit “(Kissed You) Good Night,” he picks up a bikini-clad Cavallari who throws her legs around his waist.

A source exclusively tells Pvnew that Cavallari and Estes “aren’t official yet,” though they’ve “been talking” for several weeks.
“Kristin thinks Mark is super hot. He’s very flirtatious, and she’s loving it,” the insider elaborates. “They were down in Mexico for just a few days but had a lot of fun together. It’s still new.”
According to his Instagram bio, Estes — a Montana native who used to play football for Montana State University and Montana Tech — is based in Nashville, while Cavallari resides in nearby Franklin, Tenn.
In November 2023, he commemorated his last college football game before transitioning into a fun-time career as a model.
“What a ride. 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 wrote alongside a photo of himself playing the sport.
Estes’ exes are unknown, but Cavallari has reportedly dated several notable men since filing for divorce from ex-husband Jay Cutler in 2020.
The mom of three — who shares sons Camden, 11, Jaxon, 9, and daughter Saylor, 8, with he former NFL star, 40 — has been linked to comedian Jeff Dye, country singer Chase Rice and Bachelor Nation hunk Tyler Cameron.
In June 2023, Cavallari told E! News that dating wasn’t a priority.
“I’m not overwhelmed, because there’s not a lot going on. It’s really not important to me right now. It’s just not with where I’m at in my life,” she said at the time, stressing that she’s a mother “first and foremost.”
The “Hills” alum elaborated, “I’ve had a lot of fun in the last few years, just really focusing on my friends and getting to hang out with my friends again, because I didn’t get to do that for a long time.”
