Kristin Cavallari Laughs at Acting 'Like a Little High School Girl' When 24-Year-Old Boyfriend Slid into Her DMs

The mom of three spilled some tea about the origins of her relationship with Mark Estes on her podcast on Tuesday

Kristin Cavallari is opening the lid on the blossoming love story between her and her new boyfriend.

On Tuesday’s episode of her podcast, Let’s Be Honest with Kristin Cavallari, the Laguna Beach alum, 37, revealed how she and Mark Estes first met, gushed about their time together and explained the reasoning behind her hard launch of the relationship on Instagram last month.

Cavallari admitted that she first discovered Estes, 24, while “scrolling on TikTok” as she stumbled upon the group he’s part of, the Montana Boyz, who boast over 12 million likes on the app. “So I go, ‘Holy s---, who are these guys, because they’re so hot, but specifically this one,’ who I’m going to refer to as Montana. I send it to you, and we’re both like, ‘This is the hottest guy we’ve ever seen.’”

Cavallari’s BFF Justin Anderson, who joined her for the episode, added of Estes: “If someone could draw your type, that’s your type.”

“He is. You know what it is, too? He’s gorgeous, it's like everything about him is perfect, but he's also outdoorsy and manly and it's like that combination of the two for me is just, like, game f---ing over.”

She continued, “So we both go, ‘This is the hottest guy we’ve ever seen in our entire lives, but like, okay.’  We carry on with our lives. Three weeks later, I get a DM on Instagram from the Montana Boyz that just says ‘I love you.’ And I’m going, ‘Oh, my God!’ ”

Anderson described her reaction as akin to “a little high school girl,” to which Cavallari didn’t disagree.

She began organizing for the group of boys to come on her podcast, and then her assistant told her the boys were moving to Nashville. Cavallari said that because she knew they’re “young,” she was only thinking about collaborating with them on the podcast. “I was like, they’ll come on the podcast, it’ll be a fun flirt, that’s it.”

She and Estes, whom she referred to exclusively as “Montana” throughout the episode, began talking more after she sent a DM to the account in December and mentioned their move to Nashville.

“I asked which one I was talking to and he said, ‘This is Montana responding.’ And I said, ‘Oh, good. You're my favorite.’”

Cavallari met the group of boys in person for the first time on a night out in Nashville, though she said she “still did not think anything would ever happen.” She brought some of the “young girls” who work for her out line dancing and met up with Estes and his friends one night. “And then, he asked me to be his Valentine,” she admitted. “It's cute.”

On their first date — which took place on Feb. 13, because Cavallari had dinner plans with her kids on Valentine’s Day — Estes picked her up and met her three kids Camden, 11, Jaxon, 9, and Saylor, 8, and her mom, who was over to babysit. (She shares her children with her ex-husband, Jay Cutler.)

“He came, he brought me flowers, picked me up, we went to dinner, it was very sweet,” she recounted of their first date, which ended with them “making out in my driveway.”

“I felt like I was in high school,” Cavallari admitted.

When it came to sharing the news of their relationship more widely, Cavallari said that she got a tip from her publicist that TMZ was going to spread the news of her boyfriend after they'd obtained a photo of the pair together at the airport.

"I get in a mood, I'm like f--- it," she said, before admitting that "it was a little early to hard launch someone, 100 percent. However, [as] we've been talking about, I feel very different with this man."

"I was just like, you know what? I've been in this business for 20 years," she added. "The media has always like controlled the narrative to a large degree. And part of me was like, I wanna take it in my own hands."
