Kelly Clarkson has guests on her eponymous talk show on a regular basis, but another guest joining her for the show's opening Kellyoke bit is unusual. The former Voice coach sang a duet of her Billboard Hot 100 top 10 hit ‘Breakaway’ with fellow pop hitmaker Sam Smith on an episode of 'The Kelly Clarkson Show'.
