Kim and Kourtney Kardashian Show off Their Figures in Bikinis — Fans Think Kourtney Is Pregnant

"Keeping up with the Kardashians" star Kim caused a stir with her latest Instagram post. The reality star shared a picture of herself and her sister Kourtney posing in bikinis, but fans noted something else about Kourtney's figure.

The Kardashian sisters recently enjoyed a sunny vacation which resulted in plenty of jaw-dropping bikini pictures shared on Instagram. On Monday, February 15, Kim Kardashian delighted her fans with new pics of herself and Kourtney Kardashian.

The snaps showed the reality TV sisters enjoying some fun in the sun in tiny bikinis that showed off their curvy figures. While both women looked stunning in the beach candids, fans speculated about Kourtney's body.

BEACH BABES

In the throwback photos, Kim, 40, and Kourtney, 41, were captured looking fresh with no make-up while posing on the white sandy beach with huge multiple-story houses in the background. The post was humorously captioned:

"It’s a thin line between love and hate ♥️? JK JK [sic]."

Kim rocked a classic brown bikini which showed off her ample cleavage, tiny waist, and curvy hips. Kourtney, who stood next to her, wore a black vinyl one-shoulder bikini top with a matching bikini bottom and a black cap.

The famous sisters seemed to be enjoying their time on the beach with the wind blowing in their long dark hair, and fans took note of their joyful mood and playful nature.

IS KOURTNEY PREGNANT?

However, several fans had more to say about Kourtney's body and questioned if she was pregnant again. Some fans even asked if she was carrying her ex-boyfriend, Scott Disick's baby.

Some loyal fans came to Kourtney's defense. "It's called a stomach mate," responded one fan, while another added, "You guys are all [tripping.] That's just shadows.. she is definitely NOT pregnant!"

KOURTNEY'S LOVE LIFE

Neither Kourtney nor Kim addressed the pregnancy question, although it is unlikely that she and Disick are expecting a baby together. The pair share three kids, Mason, 11, Penelope, 8, and Reign, 6, but they are not currently dating.

Since their last break up in 2015, both Kourtney and Disick have dated other people. Disick recently went Instagram official with his girlfriend, Amelia Hamlin, 19, the daughter of "The Real Housewives of Beverly Hills" star Lisa Rinna.

Kourtney has also moved on from the 37-year-old socialite and is dating Blink 182 drummer Travis Barker. Previously, she dated Algerian model Younes Bendjima, 27.

KIM AND KANYE

While Kourtney's love life heats up with a new romance, her sister Kim's marriage to rapper and fashion designer Kanye West seems to be headed for divorce after six years.

The SKIMS founder shares four children with West, North, 7, Saint, 5, Chicago, 3, and Psalm, 1, and ever since the rumored split, she has been focused on the future and her children.
