Mr. Know It All is the single from her fifth and upcoming album Strong, which will be released on October 25.  The single will be available through download on September 5.

 I think this is going to be a really awesome song! posted one users on her Web site.

I cannot wait to hear your amazing voice sing these awesome lyrics. Seems like you ain't messing around on this album Kelly! Kick some butt!!! posted another.

Over the weekend, there was considerable buzz around the song Mr. Know It All because an audio version of it was leaked online (it has been taken down as of Monday).

I wanted a rockier edge. But oh well, that voice, I love it so much! :), wrote a commenter on digital spy, which embedded a copy of the leaked song. 

Weeks ago, other demos from her upcoming album were leaked. 

In an interview Entertainment Weekly regarding these earlier leaks, she said: Oh my God, have you ever been robbed? I have. I've been physically robbed a couple of times, but this is much worse.

There are songs out there that are from eight or 10 years ago...People are always asking me to write for other artists. They're awesome songs, [but] they're just not songs I would normally sing, she said.
