Kristin Cavallari Channels Britney Spears in a Sexy Snakeskin Bikini

Kristin Cavallari has rock hard abs.

Cavallari, 39, showed off the itty-bitty Resa outfit she wore during her first-ever Uncommon James fashion show via Instagram on Thursday, May 29. Ahead of hitting the runway - during Miami Swim Week - and putting her delicate jewelry line on display, the Hills alum rocked a snakeskin look featuring a balconette bikini top with underwire cups and thin straps.

She styled it with matching bottoms that tied in bows at her hips and a sarong. Cavallari styled her Britney Spears-inspired look with a beaded necklace with a gold pendant, matching cuff bracelets, and nude heels.

For glam, the jewelry designer donned a full beat including smokey eyeshadow, bronzed cheeks and pink, glossy lips. Her blonde hair was parted down the middle and styled in beachy waves.

"We did a thing," Cavallari captioned a reel of her strutting down the catwalk. Her celebrity friends and fans praised her in the comments section.

"This feels like I'm a slave Britney came back to give the world what we needed right now in pop culture honey omg omg omg yessss 👏👏👏🔥," hairstylist Justin Anderson wrote, referring to Spears' 2001 hit, "I'm a Slave 4 U." Heidi Montag added, "🙌🔥🔥🔥🔥🔥🔥🔥🔥🔥." A fan also commented, "Kcav will always be THAT girl 😍🔥."

Ahead of the show, Cavallari took her fans backstage via her Instagram Story. "Backstage craziness!" she said while showing the chaos surrounding her. "Getting ready to walk. I'm so nervous," she added while letting out a squeal of excitement.

"First runway show let's gooooo," she captioned the post.

Cavallari also opened up to Extra TV about her runway on Thursday during a yoga event she hosted that morning. "I'm so excited to be hitting the runway tonight, " she said while smiling. "I had this idea months ago and I reached out to Suzanne [Marchese] at Resa. They're doing all the swim and we're doing all the jewelry and I just thought it would be a really great way to showcase our new collection."

Cavallari added that she maintains her bikini body by "not drinking alcohol, eating really clean, getting a lot of sleep [and] working out consistently."
