Kourtney, Kim, and Khloe Kardashian took their feud from TV to Twitter on Sunday night while live tweeting the Season 15 "Keeping Up with the Kardashians" premiere Sunday night.
Viewers watched the sisters fight about their schedules while coordinating the famous Kardashian Christmas card photo shoot, prompting Kim to tell her older sister Kourtney that she is the "least exciting to look at" and threw shade at her for not operating a business. The spat went down months ago, but it flared up again in real time after Kourt tweeted, "We all have our own priorities. Mine is being a mother."

Kourtney Kardashian Fires Back at Kim for Saying Older Sister 'Doesn't Want to Be a Kardashian Anymore'
View Story"And mine is not?" Kim responded. "The shoot was with our kids!!!!! My #1 priority is being a mother as well and I can work too, so can you!"
Kourtney fired right back, "And I do. But I wasn't wanting MORE work, I already felt spread thin. Being a good mother also has different meaning to each of us. You're an amazing mother, I'm not taking that away from you."
In the fight that was captured on camera for the episode, Khloe entered the storm as Kim threw shade at Kourtney for not having her own business.
"Maybe if you had a business that you were passionate about then you would know what it takes to run a f---ing business!" Kim yelled at Kourtney. "But you don't, so don't even act like you know what I'm talking about!"
This was about when Khloe piped up in the conversation on Twitter Sunday night, asking for "peace" between her sisters. Kourtney's response, however, just ignited more drama.
Kourtney also tweeted that she was disappointed that momager Kris Jenner sided with Kim during the fight.

After fans jumped in on the feisty discussion, Kim stressed the sisters are actually all good despite their public feuding, and the other two followed suit.
Kim and Kourtney both stressed that this season focuses a lot on "personal growth" for the sisters.
