Kourtney Kardashian In Birthday Bikini Looks 'Fabulous For 45'

Kourtney Kardashian proved popular as she showed off her sensational figure in April. Enjoying a sun-drenched day at the beach as she celebrated turning 45 years old, Kourtney stunned in the sun, and fans seemed to think she looks better than ever. As her sisters continue to raise eyebrows with endless plastic surgery allegations, Kourtney seems to be flying the flag for being the "natural sister," and fans seeing IG this post certainly appeared to think so. At the time of the photos, the star was less than six months into being a mom of four — in November 2023, she and husband Travis Barker welcomed their first son Rocky.

Scroll for the photos. Soaking up rays as she enjoyed a vacation and posed from a white-sand beach, Kourtney pouted as she lifted her arms to frame her chin while sitting on a blue lounger.

Sizzling in a printed, multicolor bikini from luxury designer Dior, the Lemme founder flashed her killer cleavage and impressively toned tummy, also showing off her gym-honed legs as she glowed in the sunshine. Donning statement shades as she wore her dark hair tied back, Kourtney sat with her accessories next to her, keeping her vibe light and making sure to include her family in her gallery.

Sitting in a tee and bikini bottoms as she got all sandy in the next photo, Kourtney Kardashian featured son Reign, shared with ex-boyfriend Scott Disick. Further slides included a family pool photo, night-time fireworks, plus a photo of the swanky villa she'd rented out for her break.

A tender moment also got fans talking as Blink 182 drummer Travis was photographed holding baby Rocky and with Kourtney sweetly looking at her son as she wrapped an arm around Travis.

"45 years around the sun," Kourtney wrote as fans left her over 1.6 million likes. "I like Kourtney’s postpartum body she actually looks like a regular human being," a popular reply read. Husband Travis also swooped in to tell his wife that "45 never looked so good."

The snaps quickly made The Daily Mail's headlines, where users were once again floored. When one fan said that they "prefer" Kourtney's figure to her sisters, another jumped in to say: "

"Right! She’s perfect! Im no super fan or fan for that matter. But I am a mom. And gurl looks fab for 45 and 4 babies. Kourt has never used a surrogate to make her any of her babies either. So she looks real good! Keep shining, Kourt. Blind em!" It's worth noting that 43-year-old Kim Kardashian's last two pregnancies required a surrogate for medical reasons as it was unsafe for her to carry any more children. Kourtney Kardashian has an estimated $65 million net worth.
