It is SO back on between Kim Kardashian and Taylor Swift.
It's just not exactly clear why.
Well over a year since Kardashian first hurled major shade at Swift by exposing her as a liar, the reality star has seemingly reignited everyone's favorite Hollywood feud.
By sharing a certain throwback photo on Instagram.
Scroll down and all around to see what Kardashian shared; to see how folks are reacting; and to relive the highlights of this much-publicized rivalry...
On December 4, 2017 Kardashian shared this Instagram photo of her snapping a picture at the 2016 "Famous" exhibit that featured the wax figures of her nude husban... and a naked Taylor Swift.
"Famous," Kim wrote as a caption, although most followers instantly interpreted it as a shot at Swift, labeling Kim a rat and Taylor a snake... and going back and forth on whose side they are on.
So... Many... Rats
As you can see, no one on Instagram thought this was just a harmless throwback photo. It's just unclear why Kim wanted to stick it to Taylor again.
Now We Revenge!
Down with the rat, right, folks?!?
How Did This All Begin?
In July of 2016, Kardashian released a recording of Swift giving Kanye West permission to rap about her in his track, "Famous." Swift had previously acted all pissed off about West's references to her in the song, leading many to believe Taylor was nothing but a phony and a liar.
A Swift Response
Swift said the leaked recording did NOT feature her giving Kanye permission to slam her as a "bitch," adding, famously, that she wanted to be excluded from all Kimye-related narratives.
