Kristin Cavallari Shares Sweet Pic of Boyfriend Mark Estes With Her Son

The former reality star of 'The Hills' shares three kids with her ex-husband, Jay Cutler.

It looks like Kristin Cavallari's kids are bonding with her new man. The Laguna Beach alum shared a sweet snap of what appears to be boyfriend Mark Estes walking and talking with one of her sons. 

In the shot, Estes and the young man are photographed from behind as they stroll side by side down a corridor. She added a simple white heart to the image, seemingly offering her stamp of approval on the heartwarming moment. 

Cavallari's post comes just one week after she opened up about the couple's whirlwind romance on her podcast, Let’s Be Honest With Kristin Cavallari, revealing that the TikTok star in fact met her children and her mom ahead of their very first date on Feb. 13. 

The Uncommon James founder shares three kids -- sons Camden, 11, and Jaxon, 9, and daughter Saylor, 8 -- with her ex-husband, Jay Cutler. The former couple was married for seven years and together for 10 before calling it quits in 2020. 

Roughly two years after finalizing her divorce from Cutler, Cavallari, 37, hard launched her relationship with Estes, 24, last month.

A source told ET at the time, "Kristin and Mark have been taking things slowly and were keeping things private until the news broke today. Both responded to the rumors, and are fine with the news about their relationship now being public."

In an Instagram post confirming the relationship, Cavallari shared a photo of the couple enjoying a sun soaked vacation together in Cabo.

"He makes me happy," Cavallari wrote in the caption.

In a TikTok video posted later by Estes, the duo playfully showed off the dynamic of their relationship while lip synching and acting out the lyrics to Gloriana's "(Kissed You) Good Night."

"Ready to fall," he wrote in the caption.

Prior to Estes, The Hills alum was previously linked to comedian Jeff Dye, singer Chase Rice, and The Bachelor star Tyler Cameron following the end of her marriage.

On her podcast last week, Cavallari confirmed that she discovered her new beau on social media. 

Estes is part of a content creation team known as the Montana Boyz, who post videos about their lives on a Montana ranch. The group has more than 630,000 followers on the social media app and it was while Cavallari was "scrolling on TikTok" that she found her new beau. 

"So I go, 'Holy s**t, 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,'" she told best friend Justin Anderson, a guest on the podcast episode. 

"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**king over," Cavallari continued. 

Turning to their 13-year age gap, Cavallari insists that age is just a number in this case and that it was never her intention to enter into a relationship with someone much younger than her. 

"Me dating a 24-year-old is not something that I was searching out. It's not something that I at all ever thought would ever happen," she admitted. "I understand what it looks like to the outside world. I really do. I get that."

Cavallari added, "He is not a typical 24-year-old."
