Kristin Cavallari's New Boyfriend Mark Estes Shows Off Their Relationship in Lovey-Dovey TikTok

The 'Laguna Beach' alum hard launched her new relationship with the 24-year-old on Instagram on Tuesday

Kristin Cavallari’s new boyfriend is itching for a kiss!

The mother-of-three made her debut on beau Mark Estes’ social media on Tuesday as the 24-year-old former football player shared a TikTok with Cavallari, 37, from their romantic getaway in Mexico.

In the TikTok, the couple sang along to the words of “(Kissed You) Good Night” by Gloriana as they stood in front of a pool with the ocean behind them and a bright blue sky above.

“I shoulda kissed you,” Estes, in swim trunks and a backward baseball hat, began lip-synching to Cavallari, who was dressed in a green bikini. He then pretended to playfully push her toward the pool, at which she laughed, as he continued to sing along, “I shoulda pushed you up against the wall.”

“You shoulda kissed me,” Cavallari then joined in, lip-synching along before Estes pulled her in for a kiss.

The Laguna Beach star then rolled her head back with a laugh before hopping into the Montana State University and Montana Tech alum’s arms. From there, Estes carried her toward the camera, his arm wrapped securely around her torso, and one hand at her lower back.

Cavallari was nonstop smiling in the short clip, the latest content shared from her and her new beau’s romantic getaway in Los Cabos, Mexico.

Earlier that day, the Uncommon James founder hard-launched her relationship with a selfie on Instagram, writing in the caption, "He makes me happy 🤍."

Estes then shared the post on his Instagram Story and added two hearts. The shot, taken by him, sees Cavallari smiling softly as she sits next to Estes in a restaurant, while he grins at the camera, too, wearing a baseball hat backward.

Many of The Hills star’s friends celebrated her new love in the comments of her post, with Rachel Bilson writing, “🔥🔥🔥” and Kaitlyn Bristowe sharing some of the lyrics from Natasha Bedingfield’s “Unwritten,” which served as the theme song for The Hills.

“FEEL THE RAIN ON YOUR SKIN,” the former Bachelorette star wrote.

Bethenny Frankel weighed in, too, writing, “Does anything else matter? ❤❤❤ be happy!”

Estes lives in Nashville, according to his Instagram bio, which is where Cavallari currently resides.

In November 2023, he celebrated playing his final collegiate football game after six years, which included one redshirt season.

"What a ride. Thankful for the last 6 years of what this sport has brought me. Thanks to all the coaches and brothers I met along the way ❤️" he captioned a photo of himself on the field.

The relationship is her first public one since her 2020 separation from Jay Cutler, who she had been married to for 7 years at the time of their divorce. The pair share sons Camden, 7, Jaxon, 5, and daughter Saylor, 4.

“With great sadness, after 10 years together we have come to a loving conclusion to get a divorce. We have nothing but love and respect for one another and are deeply grateful for the years shared, memories made, and the children we are so proud of,” she wrote as she announced the split on Instagram. “This is just the situation of two people growing apart. We ask everyone to respect our privacy as we navigate this difficult time within our family.”

Cavallari was later briefly linked to comedian Jeff Dye.
