During the Christmas celebrations on Tuesday (25 December) Sia unveiled some of her plans for the new year to an inquisitive fan on Twitter.

Responding to a fan who asked when new music will be arriving, Sia revealed, "Next year I'm releasing an album and a feature length musical I wrote and directed."

Sia is yet to follow up last year's festive album Everyday Is Christmas, and 2016's This Is Acting album.

Throughout the year Sia teamed up with Dolly Parton for Dumplin' movie track "Here I Am", as well as releasing a solo single "I'm Still Here". She's also contributed a track to Natalie Portman's new musical film Vox Lux.

Her most recent single is "Mountains" with Labrinth and Diplo as LSD. Diplo teased last week that new music from LSD would be arriving in January 2019.
