Kelly Clarkson has finally unveiled her long-awaited new single, 'Mr. Know It All'.

The American Idol superstar's forthcoming album has experienced numerous setbacks, but fans were treated to a taste of her new material when this new track was released to the public on August 30. 

It's a midtempo, sassy offering with an anthemic chorus that cements Clarkson's return with confidence and maturity, and the track itself was cowritten by Brett James (who has previously written for country sweetheart Carrie Underwood), Ester Dean (Usher, Beyoncé) and Brian Kennedy (Rihanna, Chris Brown).

Clarkson's fifth studio album, 'Stronger', is due for release on October 25 and you can check out 'Mr. Know It All' below:
