Kristin Cavallari Told String Bikini Inappropriate 'With Kids' At Grill Shack

Kristin Cavallari sparked plenty of comments as she updated her Instagram in swimwear mode while enjoying family time this week. On Thursday, the reality star showed off her incredibly toned figure in swimwear, sending out vacay vibes and including plenty of food in her gallery. Sharing photos that included the three children she shares with ex-husband Jay Cutler, Kristin went eye-popping in a minuscule bikini, flaunting her shredded abs and the implants she made recent headlines for confirming she's had. While some fans commented on her enhanced chest, others noted the presence of her family.

Scroll for the photos. All smiles at an outdoor dining area, Kristin showed off the burger she'd ordered while wearing a stylish sleeveless top and jeans. Kristin didn't take long to show off her swimsuit body, though, returning from tiled flooring while in a triangle bikini with white fabrics and black string ties.

Making eyes pop with her cleavage flash, the 38-year-old displayed her assets and insanely toned shoulders, also flaunting her killer legs while rocking her briefs low rise.

Giving a nod to her love of designer brands, Kristin also donned Chloe logo sandals before sharing a pool photo and footage of kids, including her son, enjoying a water slide. Kristin also posed in her busty swimsuit with pals Justin Anderson and Austin Rhodes. Here, the trio stood poolside as Kristin added an open shirt, shades, and a hat. One image also showed the blonde bikini-clad and backed by a Grill Shack.

"Vacation mode with this Motley Crue," a caption read. The post netted Kristin over 45,000 likes overnight. While multiple fans asked for deets on Kristin's bathing suit, others referenced the boob job she recently admitted to undergoing.

"Vacation mode with the kids: here's this photo in a bikini," one fan sarcastically replied. Another said: "Not cool," although they didn't specify why. Kristin's kids, Camden, Jaxon, and Saylor, aren't featured on Kristin Cavallari's Instagram all that often. In fact, the mom of three tends to opt out of showing their faces altogether.

Kristin spoke out earlier this year about her decision to have her chest redone after discovering that her implants had ruptured.

Talking on her Let's Be Honest podcast in May, Kristin Cavallari said she "thought maybe gravity over time had taken hold, but it just wasn't how I wanted it. It just wasn't ideal."

The Uncommon James founder added: "My intuition was saying, 'Redo your boobs. Go get your boobs checked out. At least get a consultation.' And I can't tell you why, but something in me was telling me to do it."

Pulling a Kylie Jenner (the makeup mogul recently dished all the deets on her augmentation), Kristin also told fans: "I was 340 cc before now I'm 400."
