You already saw Mariah Carey treat some loyal lambs to a surprise performance of her new single, 'The Art of Letting Go.' Now, see her hilarious improvised performance after the taping!

Mimi showed off her sense of humor in a piano ballad, featuring accompaniment from her longtime collaborator Trey Lorenz. In the clip, she touches on her "bad side," shades 'American Idol' and Nicki Minaj ever-so-subtly (as is her specialty) and gushes over her fans. She not only sounds fantastic, she sounds hysterical.
