Producers of singer Kelly Clarkson, of 'American Idol' fame, announced early Thursday that they had been forced to cancel the singer's performances in Israel due to a severe throat infection. She was supposed to perform in Tel Aviv on Saturday night and Sunday. Reportedly, the singer had been feeling ill for several days and previously cancelled a gig in Paris. She recovered somewhat and went on to perform in Berlin but then her condition deteriorated and doctors advised her to call off her Israel concert dates.
