Kristin Cavallari, 37, claps back at critics after debuting relationship with Mark Estes, 24: ‘Are you going to arrest me?’

Kristin Cavallari had a few choice words for those criticizing her new relationship with Mark Estes, who is 13 years her junior.

While lip-synching to a TikTok audio, the mother of three asked defiantly, “So what are you going to do about it? Are you going to arrest me? Are you going to give me a ticket?”

“When they’re all up in arms that im dating a 24 year old. Andddd?” she captioned the video, which was uploaded Saturday.

The “Laguna Beach” alum, 37, had people buzzing when she was spotted on a Mexican getaway with Estes, 24, earlier this week.

Amid questions about the nature of their relationship at the time, she then took to Instagram on Thursday to share a photo of the two.

“He makes me happy,” she captioned it, confirming that they were indeed an item.

At the time, a source told us that their relationship is very new, despite posting each other on social media.

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

“They were down in Mexico for just a few days but had a lot of fun together. It’s still new.”

After their age gap raised a few eyebrows, a second source told Page Six that they were “unfazed” by the criticism.

“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.”
