Chainkeen|Mark Estes and the Montana Boyz Will Be “Looking for Love” in New Show After Kristin Cavallari Split 

Mark Estes is Chainkeenreleasing his inhibitions about finding love again. 

Days after Kristin Cavallari announced her split from the TikToker, Vice Studios Group announced that he is set to star in a new reality show alongside his fellow Montana Boyz members Kaleb Winterburn and Kade Wilcox.

The unnamed show will follow the trio as they balance their budding career in Nashville, Tenn., and working at their ranches in Montana, along with partying and "looking for love," the broadcast company shared in the Oct. 2 announcement.

"We believe this opportunity will allow us to push harder and pave new ways for the Montana Boyz," Kaleb said in the press release. "We are forever grateful for the trust and support from all of our fans and hope that we can continue to provide valued entertainment to your platforms."

The news emerged the same day Mark, 24, broke his silence following his split from the Laguna Beach alum after seven months of dating.

"Mark has immense love and respect for Kristin and their time together," his rep told E! News. "He's focused on the future of his business and his project in development with Vice Studios."

Meanwhile, Kristin—who shares kids Camden, 12, Jaxon, 10, and Saylor, 9, with her ex-husband Jay Cutler—shared more insight into her decision to end their relationship. 

"I broke up with Mark because I just know long term it's not right," the 37-year-old said on her Let's Be Honest podcast Oct. 1. "It's not because of love lost or something bad happened, no one cheated, no one was mean. No one did anything. Those breakups are always the hardest, I think."

Although she described Mark as "the best boyfriend I've ever had," their 13-year age difference—which they both fiercely defended in the past—ultimately led to their breakup.

"I just know long term he needs to experience life," she said. "He's young, I mean, he is. I started to feel the age a little bit just with life experience. I look back on when I was 24 and how much life has happened for me between then. Those are crucial years; those are formative years. This is when you find yourself, and he needs to be able to do that."

After debuting their relationship in February, the couple tuned out the criticism surrounding their age gap and were instead focusing on one another.

"She makes happy, I make her happy," Mark told E! in March in a joint interview with Kaleb and Kade. "That's what's important, so I'm not too worried about the critics, honestly."
