Singer Kelly Clarkson's forthcoming album has leaked onto the internet two weeks ahead of its release date.

The American Idol winner's latest offering, All I Ever Wanted, was due to hit stores on March 10.

But staff at the Norway division of Apple's iTunes accidentally put complete tracks available for download on its website on Friday - and now the songs are spreading across the net.

It comes just hours after U2's new CD No Line on the Horizon was prematurely offered on a digital music service run by Universal Music Group's Australian division, ahead of its February 27 release.
