If you've ever seen an episode of Keeping Up With The Kardashians, you'll know that Kourtney and Khloé make quite the iconic twosome.
In fact, over the years the pair have given themselves numerous nicknames, including Yolanda and Tawanda.
Well, the other day Kim Kardashian appeared to be treading on their territory by sharing this photo of herself with Kylie Jenner.
Which she posted it alongside this caption.
Which of course piqued Kourtney and Khloé's interests. So much so in fact, that they ended up trolling Kim in the comments.
Kourtney was the first to see the photo and left this comment.
And of course Khloé then responded with this savagery.
Before Kim asked everyone to lay off.
But this isn't the first time this week that Kourtney has trolled Kim's Instagram comments. Just a couple of days ago, Kim shared this cute photo of herself with Kourt and Kendall.
And Kourtney left this comment underneath.
Never change, ladies.
