The US singer and BBC Radio 1 DJ filmed a short segment titled 'It's Britney, Witch' during Spears's trip to London earlier this month.
The clip sees the pair riding broomsticks, Spears yielding a bloody axe and the popstar reading out the monologue from Michael Jackson's 'Thriller'.
The video was made in support of Spears's new single 'Work Bitch', which is available now in the US and on November 3 in the UK.
The single is the first to be lifted from the star's forthcoming eighth studio album Britney Jean, which follows on December 2 in the UK and day later in the US.
Meanwhile, Spears recently confirmed plans to premiere her next single 'Perfume' - which was co-written with Sia - on November 5.
