Kristin Cavallari Shares Photo Of New BF Mark Estes Already Bonding With Her Son

Kristin Cavallari's relationship with her much younger boyfriend continues to thrive weeks after she hard launched their relationship.

The "Laguna Beach: The Real Orange County" star recently put her critics to shame by showing how well her lover, Mark Estes, has become a significant part of her life. She shared a cute picture of the Montana Boyz's member bonding with her family.

On Sunday, Cavallari dropped the heartwarming image of Estes' quality time with one of her sons on her Instagram Story. The pair had their backs to the camera as they talked and walked down what appeared to be a mall.

The reality TV star let the picture do the talking by leaving it captionless, save for a white heart emoji. This adorable moment comes days after she opened up about her new relationship on her "Let's Be Honest" podcast.

Cavallari explained that she found love again thanks to TikTok, recalling how it all began last September when she was scrolling through the app and stumbled upon Estes' boy group, the Montana Boyz.

While referring to her BFF, Justin Anderson, who joined her on the episode, she raved:

"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. We're both like, 'This is the hottest guy we've ever seen.'"

Although Cavallari fell for Estes at first sight, going as far as describing him as her "type," she did not make the first move. Three weeks after discovering the Montana Boyz, she received a DM on Instagram from the boy group saying, "I love you."

The mother of three described her excitement at the DM as that of "a little high school girl," noting she was over the moon and decided to invite the boys to an episode of her podcast.

Fate seemed to be bringing her and Estes closer as she soon discovered the Montana Boyz were moving to Nashville, where she lives. This sparked Cavallari's desire to have a little fun with the boys as she communicated with them via DM.

"I was like, they'll come on the podcast, it'll be a fun flirt, that's it," she said, but that changed when she realized Estes was the one she was chatting directly with. She recalled:

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

After bonding over DMs, Cavallari and Estes finally met after the Montana boys relocated to Nashville. She met the group in person during a night out in town, but she "still did not think anything would ever happen."

To her surprise, Estes made the first move and asked her to be his Valentine. However, the duo couldn't wait until February 14 and had their first date a day before the romantic holiday because Cavallari had plans with her children for the big day.

"He came, he brought me flowers, picked me up, we went to dinner, it was very sweet," the 37-year-old recounted their first date. That wasn't all; Estes also got to meet his girlfriend's children, with Cavallari making the introductions when he picked her up at home.

"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," the doting mother of three revealed.

Weeks earlier, the "Very Cavallari" star debuted her new romance on Instagram. In the February 27 post, she looked radiant in a flattering halter-neck outfit with a beaded strap and rocked her blonde hair in loose waves.

By her side, Estes showed off his arm tattoos in a short-sleeve white top with black details and donned a blue baseball cap backward. The couple posed with their heads together, flashing heart-melting smiles for the camera.

If fans didn't get the memo, Cavallari confirmed her relationship with the Montana Boyz member in the post's caption, writing, "He makes me happy."

The comment section was filled with divided fans, with many supporting Cavallari's new relationship while others criticized their age gap. One fan sweetly penned: "When the picture came out HOT, and it's too good not to post. Hard launch!"

"I just saw pics of him without a shirt on. Congratulations," another supporter echoed, while a third commenter shared: "I need to tune into the podcast for the tea on this hot country man."

As for critics, one disapproving follower declared Cavallari was in her "cougar era." Another dubbed Estes "a college frat boy," and a third claimed the age gap gave them "the ick."
