The sister drama is alive and well at the Kardashian-Jenner households. 

Kourtney and Khloé Kardashian and Kylie Jenner partied it up at the Oscars after-party, but things didn't go according to plan. The morning after the festivities, Khloé tweeted out some shade toward her older sister Kourtney that she had "ruined" the night. 

Jenner had shared some videos on her Instagram story, and the three looked like they were having a blast, but it seems things were not as they appeared. While the trio looked stunning at the event, there was definitely some drama going on behind-the-scenes, and it will most likely play out in the next season of Keeping Up With the Kardashians, which will be the final one featuring Kourtney as a predominant player. 

Khloé Kardashian called out her sister for ruining the night. 

"Ugh why did @KylieJenner and I allow @kourtneykardash to ruin our night last night ? Ugh," the reality star tweeted. Fans have no clue what the beef could be over, because it looked as if the three girls were having a blast together. Apparently, something went down.

Then she followed it up by tagging Kourtney in another tweet. 

Khloé posted another tweet simply saying, "Oh @kourtneykardash !!!!!!" Hopefully this drama will get cleared up on next season of Keeping Up With The Kardashians. Until then, it seems they're keeping us in the dark. 

Now all of Twitter is waiting to find out what this was about. 

Many fans replied to Khloé's tweet, but one person notably ignored it — Kourtney. Kylie Jenner stayed out of it, too, and hasn't mentioned anything in her posts. Drama-hungry fans wrote, "Come through babe what’s the tea ... you can’t leave us hanging now we wanna know."

Maybe the drama was over Kourtney's decision to eat some definitely non-gluten free Hawaiian rolls. 

In Jenner's Instagram Stories, Kardashian can be seen nomming on some bread. The health-conscious celebrity is always spitting facts about a healthy lifestyle, so maybe she was upset that she caved. Of course, there should be nothing wrong with treating yourself. 

It looked like all fun and games, but clearly there was more going on behind-the-scenes.

In the videos Jenner posted, which some fan accounts shared, it looked like the sisters were having a great time. Kourtney was animatedly showing off some model shots of the ladies. Judging from Khloé's face, the conversation wasn't a positive one.  

At least Kylie and Khloé had a few laughs playing with some toys. 

The moms of cousins True and Stormi were messing around with a troll doll, just like their daughters would be. The night out was a family affair, and even Travis Scott joined in. It seemed like all was going well, but clearly something happened with the oldest of the bunch. 

Khloé Kardashian showed off her glamorous look for the night, and Kourtney left a sweet caption. 

Could the tweet be a ruse? Kourtney Kardashian commented, "My gorgeous date" on her sister's Instagram post. Maybe the drama was short-lived. Either way, I hope they made the most of their night out. Kylie was too busy figuring out how to sit in the backseat in her tightly fitted gown to worry about the drama going on around her.
