Katharine McPhee performed her new single ‘Terrified’ during an appearance on ‘The Tonight Show with Jay Leno’ last week. Video at YouTube has since been removed. The ‘American Idol’ alum posed for a photo with Jay backstage before taping the NBC program, telling her Twitter followers (@katharinemcphee):
Hey, Everyone! Here’s a pic with Jay Leno that we took backstage before the show :)

from the second I saw her on Idol, I knew she was great. The best voice in the world – Barbara Streisand, second – Katharine McPhee. And she is so beautiful!
