It all started this week when KJ roasted the hell out of Cole for looking about 12 years old when they were both 17.
"Man... I would have absolutely crushed you at age 17. Crushed. @colesprouse," KJ wrote.
Clearly, KJ was a full-blown MAN at that age, whereas Cole was looking pretty Suite Life still. Bless.
KJ took it even further when he commented on his own post, writing, "And I still would now."
Cole quickly responded, "you wouldn't even have survived the weight of my wallet b*tch."
But KJ didn't give up. He then posted the same thing on Twitter.
Cole then asked why the hell he needed to post the photo again on a different platform, and KJ responded, "to get as many followers as possible."
God this is a bromance like no other.
But it didn't end there. Madelaine Petsch joined in, taking sides with KJ. "Bahahaha still would," she wrote.
Casey Cott wrote, "I would have watched the fight from the sidelines wishing for peace amongst the school."
Mark Consuelos replied, "Kids. Keep it down."
Even the Archie Comics Insta account also got involved, writing, "guys please don't fight."
Charles Melton seems to think he would own both of them though... "I would've squashed you scrubs at the same time with both hands tied behind my back."
Lili Reinhart on the other hand, wrote, "I would've pummeled both of you p*ssies."
And to top it all off, Lorde chimed in with what we were all thinking. "Wow i'm dead."
What a ride.
