Kelly Clarkson is furious after one of her demo tracks leaked on the internet.
The Since U Been Gone hitmaker has blamed internet hackers for releasing unheard track Cleopatra online without her consent, and she's branded the perpetrators "sneaky little trolls".
In a series of posts on her Twitter.com page, Clarkson rants, "Cleopatra is NOT a song on my next record! It was written for another artist! I have no idea how it leaked, it's a rough demo, unfinished!
"I'm so tired of disrespecting, lying, sneaky little trolls that pretend to be human."
