Kelly Clarkson has postponed three more concerts after being diagnosed with bronchitis.

The first season winner of Fox TV's "American Idol" had to pull out of Friday night's show in Reno, Nev., Saturday's concert in Las Vegas and Sunday's show scheduled in Spokane, Wash., her label RCA, said in a news release.

The illness had forced her to miss two shows in California earlier this week.

All the missed concerts will be rescheduled later this year and tickets already purchased will be honored on the new dates.
