The 'Mr. Know It All' gives fans details about how they can secure tickets.
Kelly Clarkson has announced plans to play a free gig in London tonight (10th November).
The 'Stronger' singer will perform at the 200-capacity venue The Borderline, according to a message on her official website.
Tickets will be issued on a first-come-first-serve basis to fans who re-tweet a message on Kelly official Twitter account.
They must then screen-grab their re-tweet, print it out and take it to The Borderline at 4pm. The first 200 fans, who must be aged over 18, will get a wristband.
Kelly is currently in the UK promoting her new album 'Stronger', which features her hit single 'Mr. Know It All'.
