Kelly Clarkson Gets 'Feisty' In 'Mr. Know It All' Video

Kelly Clarkson shows off her many sides — sexy, glam, fun and playful, to name a few — in the brand-new, Justin Francis-directed music video for "Mr. Know It All."

The video, which dropped Monday (September 26), is a mixture of sleek performance footage and glamour shots, which play up the many personality traits of the Stronger singer. The clip even features a little something called "the Wall of Doubt," which uses real, occasionally negative headlines that have been printed about the singer.

But her favorite scene, as she told, is one where she looks super glammed up in a massive gown. "There's different sides of me, and that whole outfit was more for all the freeing aspect," she explained. "Like, there's all these different sides of you, and that was the free-spirit side of me. That's one of my favorite shots in the video. It keeps coming back to my hair everywhere."

However, the girl in that shot doesn't tell Clarkson's full story. "I think there's that free-spirit side of me, and then there's that feisty performer in me," she continued. "Then there's the funny side of me. I mean, obviously you have to be funny to have a big giant wall of doubt with actual headlines of your life on the wall. It's a little fun, a little feisty."

The lead single from her October release, Stronger, was a late addition. "It was actually the last song we recorded, and we had already finished it up," she said of "Mr. Know It All." "That song came out of nowhere. And luckily it did, because everybody fell in love with it.

"I think why I was attracted to it was, first of all, every girl has probably dated that guy, and also just in work life, I've known a lot of those people — especially in this industry," she continued. "And people that try and pigeonhole you. I think I was just attracted to that idea of being a little sassy and feisty with that message."

The track was written by Brett James (Carrie Underwood), Ester Dean (Beyoncé, Usher) and Dante Jones. Brian Kennedy (Chris Brown, Rihanna, Backstreet Boys) also co-wrote and produced the track.
