Kristin Cavallari, 37, shares pic of Mark Estes, 24, bonding with her son just one month after first date

Cavallari — who shares Camden, 11, Jaxon, 9, and Saylor, 8 with ex-husband Jay Cutler — further said Estes is the first boyfriend they’ve ever met.

“When [Estes] came to pick me up, the boys were like, ‘Can I show you my room?’ [Estes] is upstairs with my kids seeing their room,” she continued. “The boys were so excited about him.”

The mom of three added, “My kids really want to see me happy.”

During the podcast episode, Cavallari also explained she first linked up with Estes online when she found his three-man TikTok account the Montana Boyz, featuring her beau, Kaleb Winterburn and Kade Cutterwilcox.

The “Laguna Beach” star explained it took a few months for her to link up with Estes but when they finally met in person during a group hangout in Nashville, Tenn. in January, they hit it off.

“We all went out. And then, he asked me to be his Valentine,” she added.

Cavallari and Estes hard launched their relationship on social media during their romantic getaway to Los Cabos, Mexico on Feb. 27.

At first, the TV personality was critiqued for their 13-year age gap, but she has learned to ignore the haters.

“The age thing was a hang-up for me at first,” she said during last week’s podcast episode. “Now, I don’t give a f–k. And I’m all in with this guy. I don’t actually care what anyone else thinks.”
