London: Australian pop star Sia is expanding her time behind the camera by co-directing a documentary with her husband Erik Anders Lang.
Lang and producer Ryland Aldrich recently formed production company Pictures, Pictures and have lined up the Untitled Sia Documentary Project, which will give fans a chance to see never-before-seen aspects of the 39-year-old "Chandelier" singer's life, reported Contactmusic.
Details surrounding the film have yet to be released, but the news comes days after the pop star announced plans to direct her frequent video collaborator, dancer Maddie Ziegler, in new movie
"Sister", which she wrote eight years ago.
Lang is also working on a documentary about the game of golf after a crowdfunding campaign helped him raise USD 50,000 towards filming costs.
