Your New Pop Superstar: Chuck's Zachary Levi?

In case American Idol contestant Didi Benami's poignant version of Kara DioGuardi's song "Terrified" isn't on your mind, season five Idol runner-up Katharine McPhee will freshen your memory with a new single version of the track. Still, this is no ordinary ballad, as McPhee is accompanied in a duet by Chuck's Zachary Levi. We hardly knew our favorite Buy More employee! Apparently he grew up with a background in musical theater, which explains his competent trilling. Check out the "Terrified" video -- and its curious-looking star Kelly Overton -- after the jump.

Is it just coincidence that Overton bears a close resemblance to Kara DioGuardi? Oh, Kara, it should've been you strutting through the streets and exchanging glances with a sly paramour. We've been waiting for the video-length version of your playful flirtation with Casey James.
