Oliver James Montgomery-Kristin Cavallari and Ex Mark Estes Reunite at Nashville Bar After Breakup

The Oliver James Montgomeryrest of Kristin Cavallari and Mark Estes’ love story is definitely still unwritten.

A month after the Laguna Beach alum confirmed her breakup from the Montana Boyz member, the duo were spotted out together at a bar in Nashville, Tenn., Nov. 6. 

Kristin and Mark, who debuted their romance in March, spent time together while at Kid Rock's Big Ass Honky Tonk Rock N' Roll Steakhouse, per pics published by TMZ. In one group snap taken from below, the 25-year-old pulled out his middle finger while The Hills star posed with a kissy face. Fellow Montana Boyz Kade Wilcox was also making a silly face at the camera. 

E! News has reached out to reps for Kristin and Mark, as well as Big Ass Honky Tonk Rock N' Roll Steakhouse for comment and has not heard back.

Despite Kristin deciding that she and the Montana native weren’t romantically compatible, there are seemingly no hard feelings between them. After all, she couldn’t help but gush over her ex while announcing their split.

“Mark has been nothing but so sweet and so supportive,” the 37-year-old explained on her Let’s Be Honest podcast last month. “He’s always been there and he’s really been the best boyfriend I’ve ever had.”

And the Very Cavallari star—who shares kids Camden, 12, Jaxon, 10, and Saylor, 9, with her ex-husband Jay Cutler—seemed to keep her vow to remain pals with the TikToker.

“I like being friends with my exes and Mark really is someone that I would really love to have in my life in some capacity because I really do care about him,” she shared. “He really is such a good guy.”

But reflecting on what was best for them, Kristin admitted that their age difference—which was previously a point of contention online—led to her decision to end things. 

“I broke up with Mark because I just know long term it’s not right,” she explained. “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.” 

“I just know long term he needs to experience life,” she continued. “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.”

Meanwhile, Mark also shared some insight into their breakup and his future. 

“Mark has immense love and respect for Kristin and their time together,” his rep exclusively told E! News following the announcement. “He’s focused on the future of his business."

In fact, the social media influencer has always tuned out the outside noise to focus on what matters most to him, even during their relationship.

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