One day after an official sneak peek of Britney Spears' "Circus" music video was posted by her camp, another video footage from the music video set is outed. Having 40 seconds in length, the footage is claimed to be a Korean TV spot which is attached to Beyonce Knowles' "Single Ladies" promo.

The TV promo features never-seen-before scenes of the "Circus" music video. It shows Britney dancing alongside several backing dancers with ablaze fire set around them. Stopping the peek at the "Circus" music video in 0:20 mark, the footage continues previewing Beyonce's "Single Ladies" music video.

In related news, Britney Spears is gearing up to kick off a promotional tour for her sixth studio effort "Circus". She will be performing on June 3 and 4 at the O2 Arena in London. Tickets for the gigs will go on sale starting from December 5, according to BBC News.
