Bum Pipes Punk Alicia

Alicia Keys cancels concerts due to swollen vocal cords, just days after tourmate Jordan Sparks bails

Something's definitely going around the tour bus.

Thanks to a case of "swollen vocal cords," Alicia Keys has been forced to scrap a couple of dates on her As I Am tour—just a week after running mate Jordin Sparks was also sidelined for bum pipes.

Keys, 27, canceled last night's concert in Pittsburgh, as well as Thursday's show in Cleveland.

Reps for the 11-time Grammy winner say Keys "is currently being treated by a physician" and should be ready to go for Saturday's show in Columbus, Ohio.

Tickets for the scuttled concerts will be refundable at the respective venues; promoters also promise Cleveland fans will have their tickets honored at the Columbus gig.

Opening act Sparks bailed on the road show last week, due to a more severe condition, vocal cord hemorrhage. The 18-year-old Idol champ hopes to rejoin the tour next month.
