Since winning American Idol in 2002, Kelly Clarkson has been no stranger to mixing up her look - from blond to brunette, from sweet to sexy, from long to short - but People magazine still couldn't help noticing the dramatic difference between her most recent red carpet look and her off-duty style.

At the CMT Giants event in late October, Kelly sported a perfectly curled coif and polished makeup. But this week, she visited the Broadway musical Avenue Q with no visible makeup and a newly cropped, darker do.

Which look do you prefer, fans?
