Kristin Cavallari In Bikini Stuns For Hot Tub ‘Treehouse Magic’

Kristin Cavallari just updated her Instagram in bikini mode, sharing both a hot tub session and an update on her romance with boyfriend Mark Estes while going “treehouse magic.” The reality star, 37, continues to make headlines for dating the 24-year-old, and these photos were proof that their 13-year age gap isn’t a problem for her. Enjoying another getaway following her romantic Mexico one earlier this year, Kristin posted from the Bolt Farm Treehouse resort in Tennessee, opting for luxury but sticking to the state where she resides. Fans went wild, flooding the comments section as soon as the post went live.

Scroll for the photos. Making fans swipe for the swimwear action, Kristin kicked off her gallery in a no-pants sweater look as she flashed her toned legs from a balcony overlooking stunning rolling hills. Holding a glass of red wine as she looked content and relaxed, the Laguna Beach alum returned for a cozy indoor selfie, this time posing with former football player Mark, who wore a sweatshirt with the hood up.

Overlooking perfect vistas as she sat in an outdoor hot tub and under beating rays, Kristin upped the ante in the third photo, stripping down to a black halterneck bikini and gazing outward as she held a morning coffee mug. Kristin Cavallari, whose net worth is an estimated $30 million, likely didn’t have to worry about Bolt Farm Treehouse’s nightly rate, and with a five-star status, the mountain resort doesn’t come cheap.

Peeping her suite’s deep-soaking bathtub, Kristin also uploaded a fun shot of Mark posing outside the bathroom and shaping his hands into a heart as he stood by its window. The MTV favorite did return in her bikini, though, making her way out of the bubbling hot tub as she thrilled fans with her sensational bikini body. “Treehouse magic @boltfarmtreehouse,” she wrote.

Kristin, who confirmed her relationship with Mark in February 2024, had some fans trolling her, but most of the early comments appeared supportive. “THIS happiness looks beautiful on you, your aura is radiating,” one fan replied.

“Truly so happy for you. Haters gonna hate as they say. I hate that saying btw. But your happiness is palpable. Good for you girl. We’re all jealous,” another told the podcast host. “She’s serving on Father’s Day. Very fitting! Boss babe!” a third added. Kristin is best known for her now-ended marriage to ex-husband Jay Cutler. The former couple shares three children.

Kristin Cavallari dropped jaws with this bikini selfie, posting from her luxurious shoe closet as she shared an April selfie on Instagram. Going bandeau-style in a strapless white swimsuit, the TV favorite was told: “Damn girl!” as she also gained over 100,000 likes.
