After the 40-year-old “Your Body Is a Wonderland” crooner shared an Instagram photo of himself from his younger days, the 19-year-old “Treat You Better” singer decided to jokingly troll him.
“#Tbt 1998,” John captioned the pic of himself posing with a guitar. “In it for life.”
“Year i was born old man @johnmayer,” Shawn remarked.
The next day, John posted a black-and-white photo of Shawn sitting at a piano along with the caption, ‘🎹@shawnmendes 📷 ya boy.”
The two are good friends and big fans of each other in real life. Shawn even once referred to John as a “music god.”
