Khloe Kardashian and Kim Kardashian are reigniting an old fight as Khloe calls out her sister for being a "hypocrite."

On the April 3 episode of The Kardashians, the Good American co-founder called out her older sister for talking on the phone to her daughter North, who was in China with her dad Kanye West, as Khloe, Kim and their mom Kris Jenner rode in an RV to Joshua Tree to go camping, per People. While a mother talking to her child isn't normally considered a bad thing, Khloe took issue with it because Kim criticized her for doing the same thing with her own kids during the last season of the show.

As Kim chatted with North for a few hours, showing her around the camper, both Khloe and Kris appeared annoyed before the former called out her sister in a confessional.

"Like, seriously. You're the one that not even a year ago is fighting with me for saying goodnight to my child. And you are on the phone with North for a couple hours," she said, while Kris chimed in during her own talking head, "This is exactly what you criticized Khloe for doing. This is the pot calling the kettle black."

Once the SKIMS founder wrapped up her call, Khloe and Kris directly pointed out the double standard.

"We're almost there and we've spent more than half of the trip on the phone with your children. Which — I love listening to my grandkids, don't get me wrong — however you gave [Khloe] so much s--- for checking in with her kids," Kris said, to which Khloe quickly added, "For three minutes! I made sure they were short because I didn't want to be rude."

Kim said her kids being in a country on the other side of the world was a different circumstance, pointing out that Khloe would also be "[freaking] out" if she were in her position. However, Khloe had another perspective on the approach that she shared during her own confessional.

"Well there's a difference. Kim talking to her daughter doesn't bother me," she said. "'She's out of the country.' Of course you should talk to your child! But girl, don't forget what a f------ hypocrite you are," she said, jokingly adding, "You two-faced motherf-----."

Aside from the previous argument, this isn't the first time one of the sisters has called out the other for their differing parenting styles. Last year, the pair had a big fight after Kim accused her sister of "mom shaming" her over not washing her youngest daughter's hair.
