Capital Breakfast with Roman Kemp 6am - 10am
The chart has been missing Kelly Clarkson for a while, but the singer is back with a new single.
We last heard from Kelly in the summer of 2009 with her song, 'I Do Not Hook Up'.
Since then she's been away writing for herself and other artists and had a big hit in the US with 'Don't You Wanna Stay'.
The song is the first to be taken from Kelly's new album, 'Stronger'.
Take a look at the video for 'Mr. Know It All' and let us know what you think below...
