Mz. Clarkson hit the stage on Saturday, amping up the crowd of nearly 80,000 at Wembley Stadium, with that powerful voice of hers!
Check out Kelly performing her most recent single, Dark Side (above)!!!
She's always SO consistent, which is clearly one of the reasons why her career has had SUCH longevity!! Of course, her hometown girl personality doesn't hurt, either!
Take a look at the rest of Kelly's set, including Stronger and some earlier hits like Since You've Been Gone… AFTER THE JUMP!
