Shawn Mendes Teases John Mayer On Instagram

Shawn Mendes has a few things in common with John Mayer, despite the 19-year-old Canadian singer being half Mayer's age – and a sense of humour seems to be on the list.

On Thursday, Mayer posted a throwback photo of himself on Instagram showing him holding a guitar and captioned it: "#tbt 1998. In it for life."

Mendes saw this as an opportunity to playfully poke fun at one of his idols. "Year i was born old man @johnmayer," he wrote.

Mayer responded to the comment with a black-and-white picture of Mendes playing the piano and the caption: "@shawnmendes ya boy."

Mayer and Mendes have previously performed together. Last year, Mendes joined Mayer onstage during his show in Toronto, and performed a mashup of Mendes' "Mercy" and Mayer's "In Your Atmosphere."
