Kristin Cavallari is pulling a leaf out of supermodel Hailey Bieber‘s books as she tucks her brand’s beauty product into her bikini. The MTV alum promoted her Uncommon Beauty brand on Instagram this week, sharing stunning poolside photos as she stripped down to a stylish black bathing suit. Tucking a bottle of her Enhanced Pineapple Peptide Nectar into her top, Kristin channeled the vibe Rhode founder Hailey once used to promote her beauty brand, with this post also shouting out Kristin’s Uncommon James jewelry line. The 39-year-old captioned her share: “Tan lines, vitamin C + peptides,” earning herself over 12,000 likes. Kristin founded Uncommon Beauty in 2021.
Scroll for the photos. Flaunting her jaw-dropping figure in a tight, halterneck bikini in a classic shade of black, Kristin proved she hasn’t aged a day, looking fitter than ever as she highlighted her gym-honed silhouette.
Flashing her killer cleavage in her busty look, the mom of three opened her gallery without her merchandise, posing by a white drape, an outdoor pool, and the ocean behind her.
Wowing with her beachy-waved hair worn down, Kristin made eyes pop with her curves, also showing off her incredible abs after three kids. The Laguna Beach star, who now runs a successful podcast alongside juggling her businesses, returned with a bottle of her peptide product tucked into her bikini top, posting a close-up cleavage shot as she flaunted her sunkissed skin. Fans also saw Kristin holding her product as she wowed with another ab display, with the final image showing her smiling and shot in profile while poolside.
“Smoke show,” one user replied. “Hottest celeb,” another said. A third wrote: “Body goals” with a fire emoji, while a fourth couldn’t manage more than: “Daaaaaamn!”
“For me personally, I just don’t think we know the long-term effects of what we’re putting into our skin. I also live a very natural lifestyle and that would go against everything I believe in,” Cavallari told Popsugar in 2021, also revealing that she now wears less makeup than she once did. Uncommon Beauty isn’t Kristin’s most popular brand, though.
Kristin Cavallari dedicates the majority of her promotional content to her main Uncommon James jewelry brand. Telling fans it’s the “only jewelry you need this summer” with this photo, the blonde wowed with a big smile, posing outdoors and outfitted in a stylish, polka-dot sundress.
Fans went wild over Kristin Cavallari’s runway walk at Miami Swim Week in May, when she modeled this teeny snakeskin bathing suit and sarong. She earned over 60,000 likes for the above Instagram photos.
