However, Page Six exclusively reported that the duo were “unfazed” by the criticism.

Though Page Six reported in February 2024 that Cavallari and Estes’ romance was “new” and not “official yet,” it seems things got hot and heavy very quickly.

“Kristin thinks Mark is super hot. He’s very flirtatious, and she’s loving it,” a source told us, noting that the pair only started talking a few weeks before posting each other on social media.

In fact, Estes publicly described himself as “single” on Valentine’s Day, just two weeks before posting a loved-up TikTok video with the “Laguna Beach” star.

“He makes me happy,” the reality star wrote on Instagram. markestes001/TikTok

They both spend time in Tennessee

According to his Instagram bio, the Montana native, who has a brother named Cade, now divides his time between his home state and Nashville.

Cavallari, for her part, resides in nearby Franklin, Tenn., with her three children, Camden, Jaxon and Saylor, whom she shares with her ex-husband, Jay Cutler.
