Out of NOWHERE, one of his biggest fans, Shawn Mendes, dragged the hell out of him.
"Year i was born old man @johnmayer," he wrote. LOL.
Now, it looks like John has gotten his revenge on Shawn.
Just recently, Shawn uploaded a gorj shot of himself playing with a baby blue guitar. Hilariously, John commented: "How do you get your diapers to fit in those pants?"
Shawn responded, "@johnmayer hahahahaha i was waiting for you!"
