Kelly Clarkson may have lighter hair now, but she still has a 'Dark Side' -- and she brought it, as well as 'Stronger,' to the 2012 MuchMusic Video Awards tonight (June 17).The newly-svelte Clarkson rocked a blown out blonde hairdo and a black, white and gold structured dress that hugged her curves -- it accented her hazel eyes and new hair color beautifully -- as well as bright green earrings. Also somewhat unique for Kel tonight? She kept her shoes (which were super cute wedges) on!

The 'Duets' coach began the performance with a heartfelt rendition of her latest single 'Dark Side.' Of course, since it's an awards show -- which are some of Kel's favorite performances to sing -- she couldn't just do one track. Following the first verse and chorus of the power ballad, Clarkson brought out the big guns.

The powerhouse vocalist then launched into her anthem 'Stronger,' encouraging audience participation via hand claps and demands to hear them scream. Pyrotechnics, fireworks and a full band accompanied the 'American Idol' winner, but her voice was the clear star of this show.
