CLEVELAND -- Alicia Keys has scrapped a concert in Cleveland after canceling her show in Pittsburgh earlier this week.

A message posted on her Web site says the 27-year-old R&B singer has swollen vocal cords. She was scheduled to perform Thursday night at Cleveland State University's Wolstein Center.

Keys plans to perform in Columbus on Saturday night.

Fans with tickets to the Cleveland show will have their tickets honored at Value City Arena in Columbus. They can also get a refund.

Keys isn't the only one on her tour with vocal problems. "American Idol" winner Jordin Sparks was one of the opening acts, but she's now under a doctor's care and resting her voice, probably until next month.
