The I Believe I Can Fly hitmaker was slated to headline the Soulfest AZ on Saturday (25Apr15) in Tolleson, but 20 minutes before the show was supposed to come to a close, his manager came out to tell fans his client would not be performing.

In a video message posted on Facebook, Kelly says, "I'm right here in Arizona right now. Big ups to all my Arizona fans out here waiting on Kellz. But I gotta let y'all know, unfortunately, I'm not gonna be able to perform even though I'm right here in my trailer and I'm ready to go on stage. But I just got bad news that my management never told me, that they did not give me my money. I haven't gotten no money (sic) for doing this show.

"They told me they had the money, so when I got here, the money wasn't here. So it's nothing personal against my fans. This is business, y'all. And I hope y'all understand. You know, when they get they money up (sic) and they ready to do business and do business correct, R. Kelly will be back here in Arizona to give y'all the best show you ever seen in your life (sic). I love y'all and once again I'm sorry."

Despite his apology, fans were still outraged as many had waited for hours in the cold and rain at the outdoor venue. Some gig-goers even threw plastic chairs at the stage when Kelly's manager made the announcement, as seen in footage posted on YouTube.

Concertgoers also shared their dismay on local news site, with one fan writing, "Shame on R Kelly for not putting his fans before $$ and shame on the promoters for screwing us all. I want a refund of my 130 I paid for this joke of a concert!!!"

Another fan added, "THIS was a ripoff!!!! The show started 4 and a half hours LATE, the first act never showed up, the promoters were VERY shady and never paid Kelly so he didn't perform at all. So after having the crowd pay all that money, some people waited from 2 pm when the doors opened, it was raining, cold, the vendors food was terrible and expensive. I can't believe just how unprofessional this 'event' was."
