Kelly Clarkson is gearing up to unveil her brand-new single, 'Mr. Know It All,' next week, and now she's prepping fans by posting the lyrics to her first 'Stronger' release.

The singer posted an image on her official website on Wednesday, showing a page of handwritten lines, which we presume were penned by the 'American Idol' star. We haven't heard the final version of the song, but by the looks of the verses and chorus, Clarkson is back with another self-assured hit. She sings:

"Oh you think that you know me / That’s why I’m leaving you lonely / Cause baby you don’t know a thing about me / You don’t know a thing about me / You ain’t got the right to tell me / When and where to go, no right to tell me / Acting like you own me lately / Yeah baby you don’t know a thing about me / You don’t know a thing about me."

We're hoping the single will have all of the epic pop qualities of 'Since You've Been Gone' and 'My Life Would Suck Without You,' but the world will find out for sure on Aug. 30 when Clarkson premieres the tune on her website at 5:30PM ET. The single will be available for purchase on Sept. 5 and 'Stronger' will hit shelves on Oct. 25.
