"American Idol" golden girl Kelly Clarkson shocked fans at a Hollywood club recently when she performed a boozy mock striptease.
The ENQUIRER's exclusive pictures -- featured in the current issue on newsstands now -- show the "Since U Been Gone" singer's new "grunge" look as she took the stage for an impromptu routine during an Aug. 14 rock concert at the trendy Keyclub.
The 2002 "Idol" winner gulped out of a bottle of Chivas Regal Scotch whiskey with Yellowcard lead singer Ryan Key before playing air guitar with band Metal Skool.
The 24-year-old then stunned the crowd by ripping off her vest and hurling it into the audience.
"It was as if some mad scientist had cloned Kelly and created an evil twin," an eyewitness told The ENQUIRER.
"Lots of people see her as sweet as cherry pie but when Kelly took the stage she had the devil in her. She licked her fingers and pretended to rub her breasts."
