Seven years ago, the duo performed together on the Madison Square Garden stage, which made Jaden's surprise appearance at the PurposeTour extra sentimental.

Twitter user, lovelivejbieber posted a video of the legendary performance, captioned "22 YEAR OLD JUSTIN SINGING NEVER SAY NEVER AT MSG WITH JADEN SMITH NO I'M NOT CRYING."
