Even the people who hate “American Idol” know the stars of it – Clay Aiken, Ruben, that guy who sings in Ford commercials. But perhaps nobody has stolen our hearts more than Kelly Clarkson – and why not, she’s completely adorable. But behind that “Since U Been Gone” sheen, it seems there’s a burgeoning rock girl.

Just watch this video. At a Los Angeles performance by kitsch metal cover band Metal Skool, the band members spot a not-so-sober Clarkson, and her puppy Ryan Key. From there, they are egged onto the stage, where after a few jovial come-ons they suggest Clarkson should sing. Key takes this as his invitation as well … but not before they both chug-a-lug a little whiskey straight from the bottle.

What results is the most bizarre and glorious version of the Guns ‘n’ Roses classic “Sweet Child of Mine.” Warning that the language is a little rough at times, so if you’re at work, at least put in some headphones.
