Kelly Clarkson is currently in full promo mode, out pushing her forthcoming album Stronger. Yesterday she hit The Ellen DeGeneres Show.

Kelly revealed that Emmy-winning actor Kyle Chandler is her celebrity crush and expressed her disappointment that he’s taken. “I found out he’s married,” joked Clarkson. “So I can’t stalk him now.”

More importantly, she hit the stage to bang out Stronger lead single “Mr. Know It All.” In a sexy dress (hello, cleavage!) Clarkson and her band ran through the cut about a guy who seriously needs a clue. Check out the performance and a preview from the song’s video after the jump.

Below is a preview for its Justin Francis-directed video. In behind-the-scenes footage, Kelly promised we’d see “a variety of different Kellys”:

Stronger is due October 24. Are you excited for the album? Let us know.
