Kelly Clarkson Mr Know It All The X Factor Australia

Kelly Clarkson sings 'Mr. Know It All' on The X Factor Australia! Girl power! C'mon Australia vote for Mel B's girls next week. Kelly also mentored the finalists this week.

Tyla Bertolli was eliminated this week.

I'm kinda rooting for the groups with the cuties. Who's the favorite on The X Factor Australia right now?
