Kristin Cavallari sports ‘M’ necklace as Mark Estes romance heats up

Kristin Cavallari is keeping her new man close to her heart.

“The Hills” alum posted some selfies via Instagram on Friday, which showed her paying tribute to her beau, 24-year-old Mark Estes, by wearing a gold necklace that featured an initial “M” pendant.

She captioned the selfies, which had her rocking a black open-front top, with a simple “M.”

Estes showed the 37-year-old star some love in the comments section, flirtatiously writing, “Smash.”

Cavallari’s confidence-exuding selfies were posted less than two weeks after she debuted her relationship with the athlete by sharing a snapshot with him on Instagram. “He makes me happy 🤍,” she captioned the picture.

At the time, a person close to the reality star claimed they had “been talking” for a few weeks but weren’t official.

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

Cavallari has since caught some serious flack over their 13-year age difference, but defended her choice to live the cougar lifestyle in a TikTok video shared last Saturday.

“So what are you going to do about it? Are you going to arrest me? Are you going to give me a ticket?” she lip-synced in the defiant video.

Further cementing her unworried attitude, she captioned the video, “When they’re all up in arms that im dating a 24 year old. Andddd?”

Page Six previously reported that she is “unfazed” by the backlash, with an insider telling us, “They’re two consenting adults who like each other, so who cares?”

“Everyone is entitled to their opinion, but Kristin and Mark aren’t paying attention to the noise,” they added.

It’s unclear exactly how the Uncommon James founder and Estes met.

He was a wide receiver for the Montana Technological University and graduated in December 2023. He has amassed social media fame as one-third of the popular TikTok account Montana Boyz.
