Kara DioGuardi has been showing that she’s more than qualified to judge American Idol singing hopefuls by giving an amazing vocal performance of her own.

The Idol judge rocked up on Lopez Tonight yesterday, when she and Jason Reeves sang the song they co-wrote “Terrified.” The track was originally penned for Idol star Katharine McPhee and has also recently been performed by eliminated contestant Didi Benami, but we think that Kara’s version is easily as good as either of theirs.

Watch Jason and Kara perform below. We think she easily could have won Idol in her day, did you love her performance as much as we did? Leave your comments below.
