Can you believe it’s been almost a decade since Kelly Clarkson beat out Justin Guarini to become the first American Idol? And can you believe there was a time when “Kelly or Justin?” was actually a valid question?

Still the all-time reigning Idol in terms of worldwide sales and vocal prowess, Clarkson performed a knockout medley of her hits yesterday on The Ellen DeGeneres Show. Although her upcoming fifth album has been held back until September, the Texas powerhouse wasn’t holding herself back when she ran through “Miss Independent,” “Walk Away,” and “Since U Been Gone” for a lucky Florida crowd. Watch it here:

Her voice is strong as ever, her attitude still grabs you by the collar, and her hits still sound as relevant. And she looks awesome in those sunglasses, even though they’re usually reserved for irritating sorority girls.

Did you watch her on Ellen? What did you think of her performance? Is she still your favorite Idol winner, or will you reserve judgment until that new William Hung album finally comes along?
