Kourtney Kardashian Celebrates Her Appearance After Fan Comments on Bikini Pic: 'I Love This Body'

The Lemme co-founder is thankful for her body because it "gave me my 3 big babies and my little baby"

Kourtney Kardashian is celebrating her birthday and her body!

On Thursday, April 18, Kim Kardashian wished her older sister a “Happy Birthday” via social media with a bikini shot of themselves with younger sister Khloé Kardashian.

As the trio posed for a bit of fun in the sun on vacation, some Instagram users instead used the celebratory moment as an opportunity to critique the new mom — which prompted a response from the Poosh founder, 45.

“Now you know she’s not going to like this photo… lol it’s her bday Kim.. lol,” one person wrote.

After Kourtney addressed the individual, the user deleted their comment, but not before Instagram account CommentsByCelebs was able to screenshot and repost the interaction.

“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,” Kourtney replied.

Other fans stepped in to praise the birthday girl as well.

“Kourt looks so fire postpartum!!!,” one person wrote. Another added, “Kourtney’s mom bod is 🔥🔥🔥.”

The Lemme co-founder and her husband Travis Barker tied the knot in 2022. They welcomed their first child together, son Rocky Thirteen Barker, in November 2023.

The two are also parents to six kids from previous relationships.

Kourtney shares sons Reign Aston, 9, and Mason Dash, 14, and daughter Penelope Scotland, 11, with ex Scott Disick.

Barker, 48, is father to son Landon, 20, daughter Alabama, 18, and stepdaughter Atiana De La Hoya, 25, with his ex-wife Shanna Moakler.

Weeks before Rocky was born, Kourtney addressed a "medical emergency" she underwent after having an urgent fetal surgery.

In her caption, she thanked the “incredible doctors for saving our baby’s life."

"I am eternally grateful to my husband who rushed to my side from tour to be with me in the hospital and take care of me afterwards, my rock. And to my mom, thank you for holding my hand through this,” the reality star wrote.

"As someone who has had three really easy pregnancies in the past, I wasn’t prepared for the fear of rushing into urgent fetal surgery. I don’t think anyone who hasn’t been through a similar situation can begin to understand that feeling of fear," Kourtney continued. "I have a whole new understanding and respect for the mamas who have had to fight for their babies while pregnant."

In Barker’s birthday tribute on Thursday, he shared an Instagram carousel, including a photo of her lying in bed with their child.

“Happy Birthday to my beautiful wife, soulmate and best friend forever. I love you, I love our life together. Thank you for being the most amazing wife a person could ask for. Here’s to many more years of adventures together ❤️‍🔥,” he wrote.
