Despite the show being filmed months ago, the sisters reignited the fight on Twitter.
In the episode, Kim, 37, was upset with Kourtney, 39, for not making enough time in her schedule for a photo shoot for their family’s Christmas card.
She called her eldest sibling 'the least exciting to look at' and 'the most f***king entitled person on the planet.'
Kourtney replied, 'You’re a very distraught, evil human being.'
As the fight aired, Kourtney tweeted: 'We all have our own priorities. Mine is being a mother.'
To which Kim replied, 'And mine is not? The shoot was with our kids!!!!! My #1 priority is being a mother as well and I can work too, so can you!'
Kourtney clapped 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.'
One fan noted that the sisters are usually very supportive of each other, to which Kourtney replied: 'We’re ride or die. But i don’t accept the way we criticise and judge each other anymore. My personal growth doesn’t allow it.'
