Kristin Cavallari has made her new boyfriend's relationship with her kids Instagram official!

On Sunday, the 37-year-old reality star posted a photo on her Instagram Story of her new man Mark Estes walking and talking with one of her sons. She captioned the image of the pair's backs with a simple white heart.

Cavallari debuted her relationship with Estes, 24 on Instagram on Feb. 27. "He makes me happy 🤍," she captioned a photo of the couple vacationing in Los Cabos, Mexico.

Estes appears to be based in Nashville like Cavallari. He's a former football player for Montana State University and Montana Tech.

The Laguna Beach alum shares three children with her ex-husband Jay Cutler — sons Camden, 11, and Jaxon, 9, plus daughter Saylor, 8. The former spouses split in 2020.

The photo of Estes with one of her sons comes just days after Cavallari revealed on her podcast, Let's Be Honest with Kristin Cavallari, that her kids had met Estes, whom she calls "Montana" on the podcast after his Montana Boyz TikTok group.

"This is the real first guy I'd say they've met. When Montana came to pick me up, the boys were like, 'Can I show you my room?' Like, Montana's upstairs with my kids, seeing their rooms. My boys were so excited about him," she said on Monday's episode.

"I think more than anything, my kids were really excited for me," she continued. "My kids really wanna see me happy. And I've been really good about separating my dating life from their life."

The Uncommon James founder went on to say that her sons were so excited about meeting Estes that they asked for his phone number.

"And they've been texting all day, every day since. And this has been going on for weeks and weeks," she added, noting that her youngest son Jaxon isn't big on texting, so sometimes it's Estes who checks in on him and initiates conversation.

After Cavallari revealed her relationship in February, a source gave PEOPLE some details about Estes and the new romance.

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