Has hell frozen over? Are pigs flying? What on Earth is going on?
In case you live under a rock, here's why that's monumentally insane: Kylie is dating Chyna's ex and co-parent, Tyga. The two have been embroiled in a super shady social media war for a while now, with things seemingly worsening once it was revealed that Chyna had started dating Kylie's brother, Rob.
But that's all water under the bridge now. The two joined forces for a' best friends' selfie, and the internet can not handle it.
So was their beef all just one big (successful) publicity stunt? Way to break the internet, ladies.
