Let's start with the facts: Kim Kardashian and Caitlyn Jenner have historically not had the best relationship.
When Caitlyn first announced her transition in spring of 2015, Kim was super supportive of her. But then Caitlyn wrote a tell-all book, The Secrets of My Life, which included a lot of stuff about the Kardashians — and things went downhill from there.
Last May, Caitlyn confirmed that she and Kim hadn't spoken in "a long time." And then in November, Caitlyn updated that the two had not spoken "in a year."
And Kim ripped Caitlyn to shreds on Keeping Up with the Kardashians, calling her a "liar" and "not a good person."
As far as we know, things are still tense between the two — and that's why some people are questioning Kim's motives with her recent Instagram post:
The picture shows Caitlyn, before her public transition, sitting on the edge of a bathtub while Kris Jenner blows some bubbles inside it. Kim captioned the pic: "TGIF."
People are confused about the message Kim is trying to send by uploading the pic.
Some thought she meant it as a dig.
They felt like the picture could potentially be disrespectful to Caitlyn.
But not everyone was upset by the post. Some commenters pointed out that Kim loves posting throwbacks.
They felt like Kim was just celebrating a happy memory.
And others even saw the post as a sign of the family coming together.
It's not clear whether Caitlyn approved the pic — or if she would even mind it in the first place. But considering how tense things have been between the two of them in the past...nobody quite knows what to make of it all.
