Sia has previewed a new song that is also a collaboration with Kanye West.

The singer took to Twitter to reveal the news, alongside which she posted an 11-second preview of the track itself.

Titled "Reaper", this marks the second time the two have worked together following last year's collaboration on "Wolves", a song tipped to appear on West's upcoming album SWISH.

News of the single comes a few weeks ahead of the release of Sia's seventh record This Is Acting which comes out on 29 January.

40-year-old singer Sia – full name Sia Furler – released her debut album OnlySee back in 1997, but it wasn't until 2014 single "Chandelier" that the musician found a mainstream audience.

Kanye West's seventh studio album SWISH – his first since Yeezus – is expected to be released later this year. The rapper's full 'audition' for TV series American Idol was released earlier this week. It's one final stunt for the show which is coming to an end after 15 seasons.

"Reaper" will debut tomorrow (7 January).
