The countdown to the October 25 release date for Kelly Clarkson's new album, 'Stronger,' is well underway -- and now her fans have a brand new video to help them pass the time while they're marking off days on their calendars.

Clarkson has released the official clip for 'Mr. Know It All,' the album's first single, and it brings the song's empowering message vibrantly to the screen by letting her symbolically destroy all the know-it-alls, rumor-mongers, and naysayers that have dogged her during her career.

The video opens with Clarkson sitting in a room whose walls have been plastered with rumors about her, alone and plagued with self-doubt. As the music builds, she's joined by her bandmates, and she feeds off their intensity until, by the end of the song, she's tearing down those rumors and heading off into a peaceful landscape.

'Mr. Know It All' was released to radio and retailers on September 5; it's already cracked the top 20 on Billboard's Hot 100 and sold more than 100,000 digital downloads.
