AMERICAN IDOL star Kelly Clarkson has been forced to scrap another three dates on her American tour after failing to recover from a bout of bronchitis.

The singer postponed two shows in California last week (ends09SEP05) due to her health problems, but showed up for a soundcheck for a weekend (10SEP05) show in Reno, Nevada.

Unfortunately, she failed to hit the high notes and chose to scrap the show.

She has since cancelled shows in Las Vegas, Nevada and Spokane, Washington.

Clarkson did make one performance over the weekend - she was among the stars taking part in an MTV Hurricane Katrina telethon on Saturday night (10SEP05). That performance was taped before she fell ill.
