[Video] R Kelly Makes Surprise Appearance With Chance The Rapper At Lollapalooza 2014

This past weekend, some of the biggest names in music showed up for Lollapalooza weekend-long festival in Chicago's Grant Park. This past Friday, Eminem took the stage and surprised everyone by bringing out Rihanna and on Saturday, Outkast ripped the festival with their historic performance. 

Last night, Chance The Rapper collaborated with Lollapalooza and Red Bull for a live stream of his set and during his performance, he brought out his fellow Chicagoan, R Kelly, as a surprise guest. While on stage, Kellz performed snippets of "The World's Greatest," Bump n Grind," and "Ignition (remix)."

Earlier before the show, Chance took to Twitter and teased fans about his upcoming Lolla show.

"Tonight isn't performing for performance's sake. It's a Chicago thing. I love music and touring. But tonight it's for Chicago."

R Kelly also took to his Instagram page and let fans know that he would be joining Chance on stage.

"Surprise Chicago!!! Bout to kill the @lollapalooza stage with @chancetherapper !!! Watch it now on lollapaloooza redbull tv #lollalive #lollapalooza #rkelly"
