Shawn Mendes took part in a very special rendition of “Classroom Instruments” on Monday’s episode of “The Tonight Show Starring Jimmy Fallon”.

Mendes joined Fallon and the Roots to belt out his smash 2016 hit “Treat You Better”, with the show’s official Twitter page sharing a sneak peek of the segment ahead of it airing.

Mendes could be seen clutching on to some spoons as the group sang along to the song’s catchy lyrics, with Fallon even joining in for those high notes.

The vid comes after Mendes appeared on “The Tonight Show” at the end of last month, with Fallon getting jealous of the Canadian getting to play on stage in Las Vegas with his pal Justin Timberlake.

“We’re actually pretty good friends now,” Mendes revealed to a jokingly offended Fallon. “It was the coolest thing of my entire life.

“Have you guys ever done bits with him? He likes you,” Fallon then said. “I mean, he likes other people, too.”

Mendes responded, “It’s rare that he brings people on stage, so he must really like me.”
