Kristin Cavallari Impresses Boyfriend In String Bikini And Pearls

Kristin Cavallari wasn't just impressing fans as she stunned all bronzed while promoting her jewelry brand in June. Posting a beach snap to Instagram, the 37-year-old sizzled in a plunging string bikini and sarong, looking stylish as ever as she wore another of her Uncommon James pieces. Adding chic accents from a pendant pearl necklace, Kristin smoldered by beach rocks as she flaunted her killer figure, and the photo quickly caught the approval of boyfriend Mark Estes. Kristin, who is 13 years older than the former football player, confirmed her relationship in February. It looks like things are going well!

Scroll for the photos. Looking glam in a seashell-style bikini top held up by thin neckties, Kristin highlighted her curves tastefully as she stood backed by rocks and ocean waters. Flashing her sculpted abs while showing hints of her sarong, the reality star teamed her ivory-colored swimwear with her brown-and-white skirt, choosing a striped number and with a folded waist detail adding chic flourishes. Wearing an arm bangle and multiple pendant necklaces, Kristin injected some pearl action from one of her pieces, keeping things understated and elegant as usual.

Lifting one arm to her head as she delivered a direct gaze, Kristin sported her hair styled into beachy waves, showing off a gorgeous glow while flaunting an all-around tan. In her gallery, the MTV alum stuck to the same swimwear look, but she switched up her poses, eventually getting leggy as she revealed her skirt to be a mini. In a caption, she wrote: "Why not wear your pearls at the beach." Beau Mark quickly left a like, plus a comment reading: "Rawr."

Fans initially teased Kristin Cavallari for dating a younger man, but it looks like they've warmed to him. The podcast host discussed her relationship on her Let's Be Honest podcast earlier this year, stating: "I think more than anything, my kids were really excited for me. My kids really wanna see me happy."

Fans definitely got happy vibes as Kristin sizzled in this snap. Posing in a knotted bandeau bikini as she stripped down for a closet selfie, the blonde wowed as she displayed her rippling abs and curvy hips, with the post ushering in "pool days." Fans left over 100,000 likes.

Kristin Cavallari wound up trolled in this selfie with Mark, one marking the couple going IG-official. Over 2,700 fans have now liked an age-shaming remark reading: "What could a 37-year-old and 24-year-old possibly have in common." Another user called Mark a "teenage boy," with a particularly spiteful comment sarcastically saying that Kristin was "finally" showing her children on social media. The star shares her three kids with ex-husband Jay Cutler.
