Sia Promises New Album, Feature Length Musical in 2019

Sia is planning on a big 2019. In a Christmas day (Dec. 25) response to a fan who asked when we will be getting new music from the "Cheap Thrills" singer, Sia revealed that it might be sooner than you think. "Next year I'm releasing an album and a feature length musical I wrote and directed," she tweeted. "Lots of fun things to come!"

Sia has been working on her directorial debut, Music, for more than three years. The film, which is slated to star her longtime dancing muse, Maddie Ziegler, Kate Hudson and Leslie Odom Jr., is based on a story the singer worked on with children's book author Dallas Clayton. According to a recent Rolling Stone story, Ziegler will play an "autistic child who comes under the care of her sober drug-dealing sister," played by Hudson. "It's about finding your voice and creating your own family," the magazine reported.

No information was available at press time about Sia's follow-up to 2016's This is Acting, which featured such hits as "Alive," "Cheap Thrills" and "The Greatest." She was most recently heard as one of the vocalists on Diplo's LSD project, along with Labrinth.

Though she's busy, Sia -- who normally covers her face with an oversized wig or some other disguise -- was her authentic self at the Kardashian Christmas party, pulling goofy faces for the camera.
