Revealing she got sober for a whopping three months after divorcing a recovering alcoholic wasn't the only thing Katy Perry did on 'Chatty Man' this week. She also sang!

Perry performed a stripped down version of her latest single, 'Unconditionally,' and we have to hand it to her -- after the lip syncing debacle and her previous struggles with breath, pitch, choreography and more, the lady put on a good show. Clad in an iridescent silver gown, Perry sang with minimal bells and whistles -- which is a far cry from her other televised performances, which usually rely more on visuals than on vocals.

Perry's performance followed her interview, in which she revealed how she got over ex Russell Brand. “You know, I did a lot of different things," she said. "I surrounded myself with my good friends, I did this whole cleanse where I didn’t have any alcohol for three months — that was devastating — I did vitamins and supplements, and hikes and meditation and prayer.”

And maybe voice lessons, because she sounded terrific! John Mayer, you're a lucky man. Don't you forget it!
