The mother-of-four reportedly clapped back at a fan on Thursday who rudely commented under Kim Kardashian’s 45th Instagram birthday tribute to her, which showed the pair posing with Khloe Kardashian in bikinis.

Assuming the birthday girl would think the snap of her was unflattering, the hater wrote, “Now you know she’s not going to like this photo … lol it’s her bday Kim. lol.”

Kourtney Kardashian clapped back at hater over her latest bikini photo with sisters Kim and Khloe.

However, according to TMZ, Kourtney proved the troll wrong.

“I LOVE this photo!” she reportedly exclaimed.

“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,” she added.

Kourtney shares sons Mason, 14, and Reign, 9, and daughter Penelope, 11, with her ex, Scott Disick, and she welcomed a baby boy with her husband, Travis Barker, in November 2023.

The Poosh founder denounced the pressure for women to snap back to their pre-baby physiques in a candid post on her Instagram Story earlier this month.

Kardashian has fully embraced her post-baby body.

“Your body is beautiful at all stages,” she penned alongside a snap of herself swimming in Turks and Caicos.

“During pregnancy as we are glowing and growing, post-partum as we are healing and shrinking, and then that period I find hardest as our bodies are still adjusting.”

She continued, “I try to be kind to myself as my body finds a new normal.”

“The pressure put on us to bounce back when everything is new and different isn’t realistic.”

“Life is beautiful, you are beautiful. Just a little reminder (for me too). XOXO,” Kourtney concluded.

In addition to getting a special birthday wish from Kim on Thursday, the Lemme creator was also honoured in a hilarious Instagram slide show shared by her husband.

The Blink-182 drummer trolled his wife by including a photo of her sitting on a toilet in the carousel he uploaded.

The slide show also showed Kourtney cuddling with Rocky, sleeping with a mechanical pencil still in her hand and a crossword puzzle on her lap as well as a photo of herself kneeling on a bed seemingly without pants.

“Happy Birthday to my beautiful wife, soulmate and best friend forever,” Barker, 48, captioned the post.

“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.”

Kourtney responded by calling Barker the “husband of [her] dreams.”
