(August 16, 2006) -- It's Kelly Clarkson as you've never seen her before.
The 24-year-old Kelly was front row on Monday night at Hollywood's Key Club watching the Metal Skool concert with drink in hand.
And when the band noticed Kelly in the crowd, they decided to bring her on stage.
With encouragement of the band and the crowd, Kelly made her way on stage, along with her friend Ryan Key, the lead singer of Yellow Card.
And then, the world was introduced to the new Kelly.
Don't believe us? See for yourself...
