Kristin Cavallari, 37, and new boyfriend Mark Estes are already discussing MARRIAGE as she finally enjoys a stable romance after her ‘super messy’ divorce from ex Jay Cutler – who has not yet been invited to meet the 24-year-old

Kristin Cavallari is serious about her relationship with younger TikTok star Mark Estes, according to sources who claim the reality TV personality has already discussed marriage and “the possibility of forever” with her new partner.

The Laguna Beach star, 37, confirmed her relationship with the 24-year-old Montana Boyz star on Instagram in late February and quickly sparked a debate about their 13-year age difference.

However, the couple are brushing off the heat, with insiders claiming Mark has already bonded with her three children as she believes this will be a ‘long-term’ romance.

‘Kristin is happy, so people should leave her alone. She loves him,” a source exclusively told DailyMail.com. “Her children adore him and he has taken an active role in their lives.

‘His age doesn’t matter. If this were turned around and it was a 37-year-old man with a 24-year-old woman, no one would notice.”

Kristin has children Camden, 11, Jaxon, nine, and Saylor, eight, with her ex-husband, former footballer Jay Cutler.

The couple was married from 2013 until they split in April 2020, with their divorce finalized in June 2022. Kristin has since described their relationship as “toxic.”

She moved on with comedian Jeff Dye, who was arrested in front of her for drunken driving in October 2023.

The insider continued, “She had a super messy divorce with Jay and then a failed relationship, which was more of a rebound than anything.

“Jeff had big skeletons and was an alcoholic. She’s glad he sobered up, but it ended terribly.

“So far, she doesn’t know of any skeletons in Mark’s closet. She’s done her research and so have her friends.

“She wouldn’t introduce him to her children if she wasn’t thinking long-term with him.”

They continued, “Mark is hot husband material and whether or not it will happen anytime soon, of course they’ve talked about it.

‘No couple enters into a serious relationship without discussing the possibility of eternity. They both want forever.”

As for whether her new man will cross paths with her ex-husband, the source added, “Mark hasn’t met Jay yet and there’s no reason for him to do so yet. Of course he knows when the kids talk about him and he sees the news.

“But that’s not something Kristin wants to mix. He wouldn’t be on the guest list at any of her weddings.’

The MTV star previously stated that shShe had dismissed the “red flags” she saw when she was engaged to Jay.

She canceled their planned wedding in 2011, two years before they tied the knot.

When they filed for divorce in April 2020, she cited “irreconcilable differences” and “inappropriate martial behavior” as grounds for the split.

Claims of infidelity spread as the estranged couple became embroiled in a bitter custody battle over their children after Kristin filed for sole custody.

Jay fought back and eventually the couple agreed to be named “joint primary residential parents,” each spending 182.5 days a year with the children.

But Kristin is clearly in love with her new man, telling her followers that he “makes me happy” when she debuted him on Instagram earlier this year.

Mark only recently became known as one-third of The Montana Boyz, a group of TikTok stars consisting of him, Kaleb Campbell Winterburn and Kade Wilcox.

The trio is originally from Montana, but moved to Nashville, Tennessee, where Kristin currently lives.

In a recent episode of her podcast: Let’s be honest with Kristin CavallariKristin revealed that the couple met online after Mark accidentally sent her “I love you” from Montana Boyz’s Instagram account.

Kristin later joked that it was a good thing “because (she) would never have seen it” from his personal story.

“I (direct messaged) Kristin and I immediately said ‘I love you,’” Mark recalled, which Kristin noted happened sometime in September or October 2023.

“I saw you guys on TikTok and I was like, who are the Montana Boyz,” she recalled. “Mark, specifically, I thought this guy is so handsome, so I sent it to my best friend and I was like, ‘Look how handsome this guy is.’

‘We were both like, “Yeah, wow, he’s amazing.” About three or four weeks later I get a DM from the Montana Boyz saying, “I love you,” and I was like, “Oh my God! It’s fate!”

‘And what should I do, because I don’t have a cold? I was like, “I want to get you guys on my podcast.” And long story short, I put you guys in touch with my assistant, who booked you guys for the podcast and then she told me you guys were moving here, and then I was like, ‘What the heck. This is crazy. .”

She continued, “I finally asked who I was talking to. And he said, “Mark,” and I said, “Oh great, you’re my favorite.”

After making their relationship public, Kristin appeared on the group’s popular TikTok account.

In the short clip, the Montana Boyz sync to Jason Aldean’s 2009 hit She’s Country as they appear to introduce Kristin as part of their posse.
