Sia's team announced this week that the Aussie star has inked a deal with Atlantic Records and is set to release a festive album this Christmas.
The Cheap Thrills hitmaker has her own label, Monkey Puzzle, but 2014's 1000 Forms Of Fear and 2016's This Is Acting are licensed through Sony.
The pop star - who is famous for hiding her face under a huge wig for anonymity - has also been working on a record of original songs with Adele's producer Greg Kurstin, which is set to drop later this year.
