Kristin Cavallari’s TikTok toy boy Mark Estes, 24, bonds with her son Jaxon, 9, as age-gap romance gets serious

Kristin Cavallari shared a photo of her new boyfriend, Mark Estes, bonding with one of her sons in a photo uploaded to her Instagram Stories on Sunday.

The Laguna Beach alum, 37 — who went public with her budding romance with TikTok toy boy Mark Estes, 24, late last month — snapped the image while strolling through a spacious building.

The media personality – who is also known for being part of the group Montana Boyz – was seen having a conversation with son Jaxon, nine, as they had their backs to the camera.

Cavallari notably shares sons Jaxon and Camden, 11, as well as daughter Saylor, eight, with ex-husband Jay Cutler.

Although Kristen didn’t add any text or caption to the photo, she simply added a white heart emoji instead.

The TV personality previously revealed that the TikTok star met her three children before the pair went on their first date on February 13.

Kristin made her relationship with Mark public late last month in February by uploading a photo of the couple during a trip to Cabo San Lucas, Mexico.

She wrote the caption for her then 4.7 million followers: “He makes me happy,” followed by a white heart emoji.

The photo showed the couple cozying up together for the selfie as they sat in what appeared to be a restaurant.

Around the same time, Mark also took to his own TikTok page to share a short clip of him and Kristin lip-syncing and dancing to the song (Kissed You) Goodnight, which was playing in the background.

The two stood next to a lush pool with the picturesque ocean nearby in the distance. Cavallari showed off her toned frame in a stylish green bikini, while Estes wore patterned swim trunks and a cap on his head.

At one point, the two walked over and shared a sweet kiss, after which Kristin jumped into his arms.

A source said this last month People“They have been dating for longer than people think and have kept it very private.”

‘They are serious enough now that they were ready to go public. They are really happy together. He’s been so great to her and he’s just a really nice guy.”

‘He’s not the typical 24-year-old. She’s having a great time and living her best life with him.”

Earlier this week on Tuesday in her latest podcast episode of Let’s be honest, Cavallari opened up about how her romance with Estes came about, admitting that after their first date, she “felt like I was in high school.”

In September last year she came across Mark and his TikTok group Montana Boyz. “So I say, ‘holy dude, who are these guys because they’re so hot, but specifically this one,’” the star said, referring to Estes.

Weeks later, she received a DM from the group on Instagram that simply said, “I love you.”

Her podcast co-host, Justin Anderson, then revealed that Kristin had been acting “like a little high school girl,” and she responded with, “I’m a holy s**t and because I don’t have a cold, I was like, “I want you on my podcast.”

The fashion designer also discovered from her assistant that the group had plans to move to Nashville, where the TV personality currently resides.

Both she and Mark continued to communicate until they met in Nashville and went on their first date on February 13.

“He came, he brought me flowers, picked me up, we went to dinner, it was really sweet,” the beauty said, adding that they “kissed” at the end of the date.

“I felt like I was in high school,” Kristin said during the episode. At one point she also added, “That attraction was always there.”

“But when I met him I thought, he’s actually a really nice, good guy. He is very sweet from the jump. He was so kind to me.’

Her decision to “hard launch” her relationship with Estes occurred during the trip to Mexico.

The Uncommon James founder explained that photos would be taken of the couple at the airport, so she opted to upload the Instagram photo of the two as well.

“It was a little early to launch someone 100 percent hard. But what we’ve been talking about, I feel very differently about this man.”

“I was like, you know what? I have been in this business for twenty years. The media has always controlled the narrative to a large extent. And part of me thought, I want to take matters into my own hands,” Cavallari added.

She also commented on their 13-year age difference, saying, “Me dating a 24-year-old isn’t something I was looking for. It’s not something I ever thought would ever happen.”

‘I understand what it looks like to the outside world. Really and truly. I get it. He’s not a typical 24-year-old.”

Their romance continues to blossom as Kristin shared a series of photos on Instagram earlier this month, wearing a gold chain necklace with the letter ‘M’ on the front.

She also hit back at trolls who were critical of her dating Estes in a TikTok with the caption, “When they’re all up in arms I’m dating a 24 year old. Andddd?’

Cavallari was previously married to former NFL quarterback Jay Cutler from 2013 until their divorce was finalized in 2022.

She commented on the divorce on her Let’s Be Honest podcast at the end of November last year and revealed she had no regrets about getting married young.

“I really think everything I’ve been through has made me who I am,” she said per We weekly. “And I mean, getting married obviously brought me my three children, but it also brought me to Franklin, Tennessee.”

It eventually led to me launching Uncommon James because I was living in Chicago and really needed something to do. And I am so grateful for that. That’s what I’m most proud of professionally.’

The star later added, “I’m grateful for it because I find that that’s where the most growth is in the most challenging times.”

‘So no, I really don’t regret anything in my life. Are there moments that I might not be proud of? Sure, but I don’t regret anything. Not really.’
