The pop star shared his plans to crash the SoulCycle session on Instagram TV, explaining he thought it would be fun to crash the event.
"I have an afternoon off and I Googled workout classes," he told followers, revealing he was put on a waiting list because the class he wanted to attend, named Jonas Brothers vs. One Direction, pitting the music of the two boybands against one another, was already full.
"The class is sold out, but I'm gonna see if I can walk in and say hi to some people," he told the camera as he documented his visit, showing him greeting the receptionist and asking if he'd be allowed in.
His request was granted, and as he walked in, the instructor remarked, "Wait, is this for real?," before introducing the singer.
"Joe Jonas, everybody! We're real right now. This is live!" she exclaimed.
The "Sucker" hitmaker was then given the opportunity to climb aboard the instructor's stationary bike to briefly lead the class in the indoor cycling challenge.
Sharing the footage on Instagram, he wrote in the caption, "When you've got an off day in Atlanta... why wouldn't you drop-in for a @JonasBrothers vs. @OneDirection class at @soulcycle?? Let's get it!"
He then made it clear his visit was just for fun as he added, "#notanad #justlovesurprises".
SoulCycle instructor Laurena Keane responded to the unexpected drop in by commenting, "First time I have gone speechless over the mic. Thank you for that epic surprise today! And to clarify, Jonas Brothers won".
