Kristin Cavallari and Mark Estes aren’t hiding their romance.

The “Laguna Beach” alum, 37, and the TikTok star, 24, were photographed in Mexico together just a couple of days after posting snaps of themselves on social media, hard-launching their romance.

The rumored new couple wheeled their luggage outside the Los Cabos International Airport Wednesday following a quick getaway to the tropical destination.

Cavallari cut a casual figure in a black cropped tee and matching sweatpants as she slung a denim jacket over her arm. The reality star accessorized the look with a gold watch, matching rings and a pair of pink, black and white high-top Nike sneakers.

The Montana Boyz member looked equally casual in a pair of black shorts with a pink hoodie worn over a black baseball cap.

Estes completed his airport ensemble with a pair of black-and-white Nike Jordans and a black backpack worn on his shoulders.

Earlier in the week, the mother of three debuted her beau in an Instagram selfie, which appeared to show them on vacation in Mexico.

“He makes me happy,” Cavallari told her followers. markestes001/TikTok

“He makes me happy,” she captioned the snap.

Meanwhile, the former college football player shared a PDA-packed TikTok video of himself and Cavallari lip syncing and making out in front of a pool.

Fans were quick to point out the 12-year age gap between the pair: Cavallari was born in January 1987, while her beau arrived in October 1999.

The pair also lip synced along to a song while filming a TikTok video. markestes001/TikTok Estes previously played football at Montana Tech, where he graduated in 2023. Instagram/@markestes

However, a source exclusively told Page Six that the duo were “unfazed” by the criticism.

“They’re two consenting adults who like each other, so who cares?” an insider close to Estes told us earlier this week. “Everyone is entitled to their opinion, but Kristin and Mark aren’t paying attention to the noise.”

A separate source noted that the romance was “new” and not “official yet,” as they only started talking a few weeks before making their dalliance public.

“Kristin thinks Mark is super hot. He’s very flirtatious, and she’s loving it,” the source told us.

The “Hills” star shares three kids — Camden, 11, Jaxon, 9, and Saylor, 8 — with ex-husband Jay Cutler, whom she filed for divorce from in 2020.

In the years since, the blond beauty has been linked to comedian Jeff Dye, country singer Chase Rice and Bachelor Nation hunk Tyler Cameron.
