Kristin Cavallari In Her Tiny Green Bikini Does A 'Fit Check' But Some Fans Aren't Happy For This Reason

Kristin Cavallari flaunted her toned physique in a captivating green bikini alongside her daughter, Saylor, in a TikTok clip!

The former "Laguna Beach" star is a mother to three children -- Camden, 11, Jaxon, 9, and Saylor, 8 -- whom she shares with her ex-husband, former NFL quarterback Jay Cutler.

Cavallari complemented her tiny black bikini with stylish après-ski fur boots, a fashion choice that has garnered enthusiastic approval. Fans are particularly praising her impeccably sculpted physique, including her defined abs, toned legs, and arms.

On February 19, Cavallari treated her 563,000 TikTok followers to a playful and flirtatious video. She showcased a dark green velvet two-piece ensemble, complete with an underwire top and low-rise tie-side bottoms.

Setting up her camera, the host of the "Let’s Be Honest with Kristin Cavallari" podcast walked backward, gracefully displaying her toned physique to the upbeat rhythm of a sped-up version of SZA’s “F2F.”

Her daughter joined in the fun, though facing away from the camera. Wearing gray pants and a black sweater, Saylor appeared with her back to the camera, engaging in playful antics as she jokingly slapped her mom's rear end.

Cavallari chuckled at the gesture and playfully lifted her leg before concluding the video.

Captioning the post with "Fit check in training," the mother of three shared.

"The Hills" alum seemed to be enjoying a family vacation in Utah, as indicated by her location tag.

Dedicated fans eagerly filled the comments section of the post, praising Cavallari for her impressively sculpted physique. They expressed admiration for her dedication to fitness and her remarkable results.

A fan pleaded, "Please spill the workout routine." And Cavallari revealed her secret: "Weights, baby! 4 times a week for an hour."

Another chimed in, writing, "Wow! You age like fine wine."

Someone else commented, "Whatever you're doing it’s working."

One person added, "Forever the it girl."

However, Cavallari's bikini update didn't sit well with everyone, particularly when her daughter made a cameo.

A TikTok user asked, "How much more attention do you need girl?" while another remarked, "That's pretty bizarre. Not sure of any other parent on the planet that would be happy to post that. Yikes."

A different fan expressed, "You look great but why post this in front of a young girl? You're showing her that it's okay."

Cavallari seldom showcases her children on social media, yet she's always been unapologetic about flaunting her physique on her various platforms.

In March 2023, the former star of "Very Cavallari" nearly burst out of a black bikini while striking a pose on a large table in dim lighting. Her hair was pulled up into a high ponytail as she sensually locked eyes with the camera.

"But she's a mother," Cavallari sarcastically quipped, adding a screaming face emoji.
