There's a reason Kygo is calling his latest tour the "Cloud Nine Tour," because that's how you feel when you're there! During his tour stop in Chicago, the producer/DJ surprised the crowd when he brought out R. Kelly to perform a few songs while at Navy Pier. 

Kygo's Chi-Town tour stop was the last show of his in North America before heading to Europe to continue the trek. After he brought out R. Kelly, the R&B superstar performed Kygo's remix of Marvin Gaye's "Sexual Healing," before he moved on to perform his own hit "Ignition." 

On Instagram, Kygo posted a photo from the concert, writing, "What a way to end the tour!! Chicago you guys were amazing! And oh, thanks to the legend @rkelly for joining me on stage."

Coincidentally, it was recently the 13 year anniversary since R. Kelly blessed us with the "Ignition Remix" ... hot and fresh out the kitchen.
