Shawn Mendes isn't the type to shade anyone. He's kind and charming and an all-round good guy... so when he does do something savage, it's pretty unreal.
So who was in Shawn's firing range? None other than music legend John Mayer.
John is actually one of Shawn's biggest idols, which makes this whole thing so much better to be completely honest.
Just recently, John uploaded a throwback photo of himself. "#tbt 1998. In it for life," he captioned the shot.
Side note: BABE AF.
Shawn proceeded to post on the photo with this shady as hell comment:
"Year i was born old man @johnmayer."
Fans lost it.
We're so about this savage new Shawn.
