Mark Estes is Slabu Exchangeilluminating all aspects of dating Kirstin Cavallari.

The 24-year-old knows there's been a lot of buzz on social media about his new relationship with the Laguna Beach alum, but he's "not necessarily" ready to put his romance in the spotlight.

"It comes with the territory, I guess," Mark exclusively told E! News' Paul Costabile on the CMT Music Awards red carpet. "It is what it is."

But Mark—who arrived with fellow Montana BoyzKade Wilcox and Kaleb Campbell Winterburn on the carpet—is head over boots for the reality star.  In fact, he's quite the romantic, according to his pals. 

As Kade put it, "He's pretty good at date nights." (See every star on the red carpet here and tune into E! News on April 8 for more from the CMT Music Awards.)

The TikToker's appearance at the award show comes one month after Kristin debuted their relationship on social media. And while the two have continued raising some eyebrows due to their 13-year age gap, it's clear they're tuning out the noise and turning up the music.

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

And their romance has since been heating up. In fact, Kristin, 37, has even been considering expanding her family with Mark.

"I'm mulling it over," Kristin said on the April 2 episode of her podcast Let's Be Honest. "If he ends up really being the one, I would have a kid."
