Kourtney Kardashian's Sexy Bikini Photo from Her 45th Birthday Leaves Husband Travis Barker Melting

Kardashian enjoyed a vacation in paradise with her husband and four kids in honor of "45 trips around the sun"

Kourtney Kardashian is feeling flirty!

On April 18, the Lemme founder turned 45 and she definitely kicked off her mid-forties in sexy style while on a birthday trip with her loved ones.

Shortly after the special occasion, the mom of four posted a bikini photo to Instagram taken on the beachside vacation she took with husband Travis Barker and her kids.

The mom of four shows some skin in a vibrant bikini top and briefs splashed in a tropical pattern. She accessorized with black sunglasses and kept her glam pretty minimal so she could soak up the sun to the fullest.

She pulled off a cute pose with her lips pursed and her hands placed under her chin.

Barker gushed over his wife, with whom he officially tied the knot in May 2022, in the comment section, writing, “45 never looked so good.”

In the carousel, shared on April 23, the Kardashians star also included a few other care-free snaps, like one of her lounging in an oversize T-shirt with her 9-year-old son, Reign (who she shares with ex Scott Disick) hanging out in the background.

She also included an aerial photo of her enjoying some pool time with her 11-year-old daughter Penelope (who she also co-parents with Disick alongside 14-year-old son Mason).

Another recent occasion that called for a rotation of swimsuits was Spring Break, which Kardashian embarked on with her sisters Kim and Khloé Kardashian and Kylie Jenner. She showed off her post-pregnancy figure in a classic black bikini.

Since giving birth to Rocky, Kardashian has embraced her curves — and has let everyone know on Instagram. In response to someone critiquing her body under a birthday tribute posted by Kim, Kardashian responded:

“I LOVE this photo! It is me and my sisters having the best time on a trip with our kids... and the memories to last forever! And I LOVE this body that gave me my 3 big babies and my little baby boy.”
