Kelly Clarkson – “Mr. Know It All” “Since You Been Gone” – Ellen Degeneres.

UPDATE: Adding a BONUS CLIP of Kelly singing “Since You Been Gone”.

Kelly Clarkson’s performance of her new single “Mr. Know It All” is even better today’s Ellen Degeneres Show than her fine performance of the tune on Jay Leno a few nights ago.

I’m loving Kelly’s new glam look too!

After, Kelly sat down with Ellen to talk about how a new yoga routine has helped her calm down and lose a little weight. Plus, more on her love of Friday Night Light’s (and recent Emmy winner) Kyle Chandler.
