Kim and Kourtney got into a public fight on Twitter during the premiere of KUWTK season 15 on Sunday night.
Maybe it was all a publicity stunt, maybe it was legit, but either way it was entertaining.
Here's what happened on the first episode:
And here's a look at the full fight between Kim and Kourtney:
Clearly the sisters were watching the show as it aired live and were upset about footage they hadn't previously seen.
Kim kicked things off with a dig at Kourtney.
You hear that??? If I don't take my meeting as scheduled then I couldn't launch my ULB KKW BEAUTY collection! AND I had this oNLY time slot to plan my baby shower, but Kourt wouldn't budge to help a sis out!— Kim Kardashian West (@KimKardashian) August 6, 2018
Kourtney hit back with a tweet about her priorities.
We all have our own priorities. Mine is being a mother. #KUWTK— Kourtney Kardashian (@kourtneykardash) August 6, 2018
Naturally Kim was hurt and replied that her number one priority is her children.
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! https://t.co/3bApFwwjcr— Kim Kardashian West (@KimKardashian) August 6, 2018
Kourtney softened the blow a little bit by calling Kim an 'amazing mother'
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. https://t.co/ZMpEo5nlwL— Kourtney Kardashian (@kourtneykardash) August 6, 2018
Keeping Up With The Kardashians season 15 continues next Sunday.
And it doesn't look like we'll be waiting too long for season 16...
Speaking it into existence! We start filming Season 16 in a few weeks! 🙏🏼 https://t.co/dmN3QcWj4E— Kim Kardashian West (@KimKardashian) August 6, 2018
