Kourtney Kardashian Playfully Trolls Kim and Khloé's Sexy Bikini Photos — and Pokes Fun at Herself

Kourtney is on vacation with Kim and Khloé in Turks and Caicos

Sisterly love!

There's nothing like trolling your nearest and dearest — just ask Kourtney Kardashian.

After Kim Kardashian took to Instagram on April 7 to show off her gorgeous vacation in Turks and Caicos with her sisters, even tagging Khloé Kardashian and Kourtney, the eldest Kardashian couldn't help but jump in and make note of her placement in the photo.

The photo in question finds Kim and Khloé, 39, lounging in the sand in their racy swimwear — both snake print of course — while Kourtney is seemingly miles behind them on a lounger.

Okay, so Kourtney's not miles away, but she's so far in the background that she's minuscule in the photo, while Khloé is prominently displayed.

Kourtney, 44, shared Kim's post on her Instagram Stories, writing, "I love taking pics with my sisters!"

That wasn't the only joke Kourtney made at Kim's expense. She also shared a couple photos to her grid poking fun at the iconic diamond earring joke from Keeping Up with the Kardashians. She captioned her bikini post, "My diamond earring came off in the ocean and it’s gone."

The joke comes from a season 6 episode of KUWTK filmed in 2010, where Kim, 43, and then-boyfriend Kris Humphries were vacationing in French Polynesia.

Humphries tossed Kim into the ocean and her earring fell out. The result? The iconic line.

“My earring’s gone!" she said " “F---! Oh my God, I’m gonna cry. My diamond earring!”

“We’re not gonna find it in the ocean!” she yelled at Humphries when he tried to help.

Kourtney was having nothing of Kim's panic, replying, “Kim, there’s people that are dying."

Kourtney also shared a more serious and meaningful sentiment on her Instagram stories, opening up about postpartum body acceptance and the importance of ignoring snapback culture in a message to other "new mommies."

"Your body is beautiful at all stages. During pregnancy as we are glowing and growing, postpartum as we are healing and shrinking, and then that period I find the hardest as our bodies are still adjusting," she began. "And if you're breastfeeding, that's a whole other part of it. I try to be kind t myself as my body finds a new normal."

The Poosh founder adds that outside pressures 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.)," she concludes.

Kourtney shares her 5-month-old son, Rocky Thirteen, with husband Travis Barker, their first child together. The Lemme founder is mom to sons Mason, 14, Reign, 9, as well as daughter Penelope, 11, with ex Scott Disick. Barker is dad to daughter Alabama Luella, 18, and son Landon Asher, 20, and stepdaughter Atiana De La Hoya, 24.
