Kristin Cavallari Is Unfazed by Outside Noise Surrounding Romance With 24-Year-Old Mark Estes, Source Says

The 'Laguna Beach' star doesn't care what others think about her new relationship with 24-Year-Old Mark Estes.

Kristin Cavallari remains undeterred by the recent uproar surrounding her relationship with 24-year-old Mark Estes. Despite facing criticism and judgment from some, The Hills alum embraces her truth and lives on her own terms.

A source tells ET, "Kristin has always been unfazed by what others say, and has always beaten to her own drum. She is thriving in life both professionally and personally and looks at the outside noise as motivation. She is living life the only way she knows how and that’s by living her truth."

In a recent TikTok video, 37-year-old Cavallari directly addressed the backlash she has received, lip-syncing to a famous clip where a woman defiantly questioned authority. The caption of the video read, "When they’re all up in arms that im dating a 24 year old. Andddd?" The video quickly went viral, amassing over three million views and sparking a conversation among fans.

Support flooded in for Cavallari, with one fan commenting, "So happy for you!!! Not what I was expecting as I religiously listen to your podcast 😜 But I know you’re not one to settle so he must be great!!" Another supporter wrote, "Why are ppl so pressed bout this? You go girl. I’m 38 and my husband is 28."

The controversy erupted after Cavallari shared news of her relationship on Instagram, posting a selfie with Estes from a trip to Cabo San Lucas, Mexico, with the caption, "He makes me happy." 

Last Tuesday, a source told ET, "Kristin and Mark have been taking things slowly and were keeping things private until the news broke today. Both responded to the rumors, and are fine with the news about their relationship now being public."

The same day, Estes used his TikTok account to share a video of his newly-debuted girlfriend, playfully lip-synching and acting out the lyrics to Gloriana's "(Kissed You) Good Night."

"Ready to fall," the 24-year-old Montana Tech University alum and minor league baseball player wrote.
