Kelly Clarkson - 'Stronger (What Doesn't Kill You)' (Official Video)

The 'Mr. Know It All' singer has launched the second music video to be taken from her new album.

Following the success of her single 'Mr. Know It All' in September Kelly Clarkson has now launched the music video for her second release from fifth album 'Stronger'.

Back in November Kelly issued an open call to fans across the world for them to submit videos of a choreographed dance routine.

The videos sent in feature as part of the music promo for 'Stronger (What Doesn't Kill You)' in what Kelly describes as a "global flash mob".
