Kourtney Kardashian throws major shade at sister Kim as she praises Khloe in new post amid bitter family rivalry

KOURTNEY Kardashian has thrown some major shade at sister Kim after she praises Khloe's new fashion collection.

Shared to the Hulu star's social media, Kourtney, 44, celebrated the launch of Khloe's, 38, Good American swimwear collection just in time for the warm season.

The KUWTK alum shared two of the many new bathing suit designs on her Instagram Stories.

"My fave bikinis are here," she captioned the photo showing off hot pink and sky blue bikinis.

Meanwhile, sister Kim Kardashian, 42, also recently released a swimwear collection for her brand, SKIMS, and has more designs coming out this week — but Kourtney hasn't said much about it.

BATTLE OF THE BATHING SUITS

Earlier last month, Kim nearly popped out of the new bikinis she showed off that is part of the new collection.

One snapshot showcased the reality TV star's fit physique as she donned the apparel company's new Sport Swim Mock Neck Top in the Taffy shade.

In another, the Keeping Up With the Kardashians alum flaunted her famous curves while donning the Zip-Up Swim Mock Neck One Piece in Cobalt.

Kim was also sure to show off her flat stomach and pencil-thin waist in the Hibiscus-colored Zip-Up Swim Mock Neck Top and Dipped Tanga Bottom.

Fans rushed to the comment section to remark on the upcoming swimwear release and now Kim looked while modeling them.

One person wrote: "So beautiful."

Another commented: "Loving all these new looks y’all are on it."

"I love the blue too, so pretty!"; wrote a third.

While a fourth commenter demanded: "Take all my money Kimmy."

Kim's newest swimwear collection will be up for grabs on May 12.

SISTER RIVALRY

Back in October, Kourtney appeared on an episode of the  podcast.

While there, she explained her feud with her sisters, Kim and Khloe.

Podcast host, Amanda Hirsch, mentioned Kourtney's formerly tight bond with her sister, Khloe.

She reminisced over the Poosh founder's previously close relationship with Khloe and how Kim seemed like the "outsider" of the group.

Though that dynamic appears to have changed with Khloe and Kim getting closer and Kourtney stepping back from the pair.

Kourtney theorized that her sisters' newfound closeness could be due to them both welcoming children simultaneously.

Kim's third child, Chicago, four, was born in January 2018 via surrogate, while Khloe gave birth to her firstborn, True, in April of that year.

The siblings also share similar motherhood journeys as Khloe followed in Kim's footsteps and went the surrogacy route to have her second child, a son, born in August.

"I just felt like they really bonded - like they were going through the same things," Kourtney explained of her sisters' relationship.

The TV star then revealed what drove her apart from her siblings, claiming they "ganged up" on her regarding her different career goals.

"And then I felt like that's when I was unhappy with the show - particularly because of them two kind of ganging up.

"Almost everything that Khloe and I had done to Kim, and they were kind of flipping it on me," Kourtney said.

The Lemme founder shared that she had also started therapy at this time, so she felt "sensitive" about the comments her sisters' were making.

Although Kourtney and Khloe are not as close as they used to be, the reality star assured listeners that their relationship is "good" now.
