They've been rumoured to be working together for ages.
Now, the first efforts from a Lorde-Kanye West collaboration has been released, with the rapper's remix of the pop star's Hunger Games theme being posted online.
West remixed Lorde's Yellow Flicker Beat, turning it into a grimy, downbeat trap song, for her Mockingjay part one soundtrack.
Called Flicker, the track has been praised since being posted on YouTube.
"This gave me shivers?," wrote one listener.
