Kristin Cavallari, 37, and Mark Estes, 24, have already discussed children amid ‘pretty serious’ romance

With Mark Estes, Kristin Cavallari sees a long future — and potential babies.

The “Laguna Beach” alum, 37, revealed on Tuesday’s episode of her “Let’s Be Honest” podcast that she would be open to having a baby with the hunky social media star, 24, if he ends up being “The One.”

“The one thing that — I’m not actively thinking about it, but it’s definitely on the back of my mind — is, you know, he wants to have a kid,” Cavallari explained. “So, you know, I’m mulling it over.”

Cavallari — who is mom to sons Camden, 11, and Jaxon, 9, and daughter Saylor, 8, with ex-husband Jay Cutler — has already brought up the idea of having another child with her beau.

“All of my kids are like, ‘Yes, do it!’” Cavallari said. “My biggest thing is, like, Saylor, my youngest, is 8. The thought of going back and starting all over again is, like, that’s a lot, man.”

However, she noted that her kids are “old enough” now that they could “help” out with a newborn if needed.

“If he ends up really being ;The One’… I would have a kid,” she said. “It’s become pretty serious, this relationship, I would say.”

The former reality TV star said she would “have to have a kid” if she wanted her romance with the TikTok star “to last.”

“By the way, it’s [because] I wouldn’t want to rob him of that, like, he should have kids in his life,” she explained, noting that she thinks Estes would be a really “hands-on” father.

Despite all the talk of baby-making, Cavallari clarified that it likely wouldn’t happen for a little while.

“I mean listen, it’s literally been a couple of months,” she said. “But when you know, you know!”

The pair went public with their romance in February while vacationing together in Mexico. Although insiders told us that the twosome were still in the early stages of dating, they seemingly fell hard, fast.

In fact, Estes met Cavallari’s kids and her mother before their first date. However, Cavallari told her podcast listeners that the social media star took the situation in stride and instantly won over her family.

“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. The boys were so excited about him,” she said last month.

“My kids are really excited for me. My kids really want to see me happy and I’ve been very good at separating my dating life from [them].”

Estes later told Page Six exclusively that he was a bit “nervous” before the date — but felt “instant chemistry” with Cavallari the moment they finally met in person.

“She’s just super confident,” the athlete, who makes up one third of popular TikTok group the Montana Boyz, told us.

“Obviously she’s gorgeous. She’s an amazing person as well, and a great mother. So, yeah, pretty much [the] full package.”
