Kelly Goes With "Never Again" for Leno

If you missed her performance on “The Tonight Show,” Kelly did not sing her new single, “Sober.” She performed “Never Again,” much to the delight of the audience. Personally, I thought Kelly never sounded—or looked—better.

Kelly did sing “Sober” after the show for the website.

You can hear “Sober” and “Never Again” at http://www.nbc.com/The_Tonight_Show_with_Jay_Leno...
