Cavallari rocked a pair of high-waisted leather pants and a white tank top with a long, beige cardigan.

She completed the look with a pair of pointy black boots, a black handbag and several layered necklaces.

The Montana Boyz member looked casual in an oversized gray tee, patterned shorts and a pair of black and white Nike sneakers.

He added a baseball cap and a long silver chain, along with a silver bracelet.

In a video obtained by TMZ, the blond beauty could be heard joking about Estes’ Celebrity doppelgänger.

“You look like…” the paparazzi began saying, before Cavallari interjected, “Heath Ledger,” referencing his resemblance to the late Australian actor.

The couple quickly got into a waiting SUV and drove away.

It comes one month after they sparked romance rumors during a romantic Mexican getaway together.

The “Hills” alum then confirmed their relationship status when she took to Instagram to share a photo of the two. “He makes me happy,” she captioned it, confirming that they were indeed an item.

Estes, whose TikTok group Montana Boyz boasts more than 700,000 followers, posted a PDA-packed video with Cavallari, which he captioned, “ready to fall.”

“Kristin thinks Mark is super hot. He’s very flirtatious, and she’s loving it,” an insider told us last month. “They were down in Mexico for just a few days but had a lot of fun together. It’s still new.”

Meanwhile, a second source told Page Six that the pair were “unfazed” by criticism of their 13-year age gap.

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

The Uncommon James founder shares her three kids — Camden, 11, Jaxon, 9, and Saylor, 8 — with ex-husband Jay Cutler, whom she split from in 2020.
