Kelly Clarkson won the first series of American Idol in 2002.

The singer had originally said her tracks could not be sung by contestants in the new series of the show.

Judge Simon Cowell said: "I think that by ignoring the show you're ignoring the audience who put you there."

But the chart-topping star has now agreed that the next generation of wannabes can use her material.

American Idol must obtain permission from owners of song licenses in order for the music to be used on the show.

Negotiations

Clarkson's record label Sony BMG said her management was in negotiations over which of her songs could be used.

Spokesman Roger Widynowski had earlier said the singer was not allowing her songs to be licensed for other purposes and he had not been informed of negotiations.

In an interview with the Associated Press agency in 2005 Clarkson said she was aware that her career started on American Idol.

"They always talk about the big first thing that you did," she said.

"I think the only thing that I do mind is I don't want people to only focus on that."

Clarkson was the first winner of American Idol when it was launched in 2002.
