Severe weather conditions forecast because of approaching Hurricane Dennis forced singer Kelly Clarkson to postpone tour dates in Louisiana and Florida.

Sold out concerts scheduled for the UNO Arena in New Orleans Sunday and the Civic Center in Pensacola, Fla., Tuesday will be rescheduled as soon as possible, according to Clarkson's management Saturday.

All tickets sold for these two concerts will be honored for the re-scheduled dates.

Clarkson, who was the first "American Idol" winner, is currently on the "Behind These Hazel Eyes Tour" that began June 19 in Wales and ends Sept. 10 in Las Vegas.
