Kristin Cavallari In Plunging Beach Bikini Congratulated On 'Best Plastic Surgeon'

Kristin Cavallari is back in her swimsuit as she shares a new vacation snap on Instagram. The reality star, 38, jetted out to a tropical destination for the Fourth of July, and she's been busy posting content from her travels with friends Justin Anderson and Austin Rhodes, plus her three kids. Posting over the holiday weekend and just after she made headlines for sharing photos of children Camden, Jaxon, and Saylor, Kristin dropped a bombshell bikini photo as she posed on the beach, and there was a strong motherhood reference in her caption. While many celebrated the MTV alum's "I'm a mommy" post, others referenced the cosmetic surgery she recently admitted to undergoing.

Scroll for the photo. Posing from a white-sand beach while leaning against a tiki hut, Kristin dropped jaws in a minuscule, printed bikini in white and red.

Opting for speck prints as she showed off her enhanced assets and toned abs, the Uncommon James founder wowed in a plunging triangle top, rocking a cleavage-enhancing halterneck that also highlighted her gym-honed shoulders. Looking fit and tan while rocking minuscule bottoms, Kristin upped her designer game in a logo pair of Chloe sandals, completing her look with jewelry from her best-selling brand.

Wearing her hair down in slight beachy waves, Kristin knocked the camera dead, but not all of her fans sent love. While the post earned over 22,000 likes overnight, it also landed the Laguna Beach alum some shade. "Must be nice to have money for the best plastic surgeons and personal trainers easy to be a mommy," one user said. Kristin made May headlines for confirming that she underwent a boob job after a ruptured implant left her looking a little uneven.

The comment didn't go ignored. Defending Kristin, another fan said: "Yeah and ?? If you want better do better quit moaning."

Speaking on her Let's Be Honest podcast earlier this year, Kristin Cavallari confirmed she'd decided to get her "boobs redone.

“Things happen so gradually. There wasn't a moment where I was like, ‘My boobs look different,’ or, like, ‘My boobs aren't laying right.’ I knew that my boobs were not laying how I wanted them to lay," she revealed, continuing that the rupture had caused scar tissue. “I was not ready to take out my implants," she added, also saying that at 38, she's still "young."

In the above photo, Kristin Cavallari showed off her braless curves in a silver minidress while promoting her podcast's tour in NYC. She added strappy high heels while flashing her killer legs, completing her look with a flawless face of glam and her hair worn down. The share earned over 40,000 likes, including a celebrity one from reality star Melissa Gorga.
