Kristin Cavallari is 'having a great time and is living her best life' with boyfriend Mark Estes, claims insider

LOS ANGELES, CALIFORNIA: Kristin Cavallari is reportedly in a relationship with her new partner, Mark Estes. The 37-year-old television personality made the surprising disclosure on her Instagram on Tuesday, February 27, with a selfie from their romantic vacation in Los Cabos, Mexico. 

An insider told People Magazine that the couple have been “dating longer than people think,” but “have kept it very private.”

How did Kristin Cavallari meet Mark Estes?

The mother-of-three met Estes, 24, on “social media,” the source said, before adding, “They’re serious enough now that they were ready to go public.”

“They’re really happy together. He’s been so great to her and is just a really nice guy,” the insider said, before adding,“He’s not your typical 24 year old. She’s having a great time and is living her best life with him.”

“He makes me happy 🤍,” Cavallari wrote in the caption of the selfie she shared with Estes, announcing their relationship. Estes shared it to his own Instagram Story with “❤️❤️.”

Kristin Cavallari and Mark Estes' romantic tropical vacation

The former college football player posted the Laguna Beach star on his social media later the same day as he shared a PDA-filled TikTok from their tropical getaway.

In the TikTok, the couple sang along to '(Kissed You) Good Night' by Gloriana as they stood in front of a pool with the ocean behind them and a bright blue sky above.

As Estes lip-synched to Cavallari, she returned the favor, and he pulled her in for a kiss. She then rolled her head back with a laugh before hopping into the Montana State University and Montana Tech alum’s arms.

From there, Estes carried her toward the camera, his arm wrapped securely around her torso, and one hand at her lower back. 

Kristin Cavallari separated from Jay Cutler in 2020

Cavallari divorced Jay Cutler in 2020. The pair had been married for seven years and have sons Camden, 7, Jaxon, 5, and daughter Saylor, 4, together.

The reality told E! News in June that dating was “really not important” to her as she was focusing on being a mom “first and foremost.”

“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,” she said.

“Really, when you're having little babies and three babies, essentially, at one point in time, that was my world. And so it's been nice to just have fun again," Cavallari added.

When asked what she would want in a partner, Cavallari said, “I want to meet someone organically.” She’d previously admitted that she was using social media to date, though she had a few parameters on that method.

"I can't filter through all of my DMs, but I can see those blue checkmarks, honey!" The Hills alum said on the Not Skinny But Not Fat podcast in 2022. "I don't like people that often, and I'm pretty picky, I guess, but I'm not gonna settle. I'm gonna stay picky," she continued.

Cavallari also added that she would prefer someone who was not famous, adding, “I really, in my head — my ideal man is a businessman who no one knows."
