Kelly Clarkson Mashes Up Already Gone & Halo!

Kelly Clarkson got into the Halloween spirit at her concert Saturday night by dressing up as Family Guy’s Stewie Griffin.

And the American Idol alum treated the audience to a mashup of her single Already Gone and Beyonce’s Halo.

Finally! They’re practically the same song, except Kelly blows Beyowulf out of the water with this one!

Listen to the mash up (below)!

Thoughts???
