Things aren't looking good for Sia and her husband, Erik Anders Lang.
According to court documents that E! Online obtained in Los Angeles, Sia has filed for divorce due to "irreconcilable differences".
The couple announced earlier this month that they planned on separating. They told the press: "After much soul searching and consideration we have made the decision to separate as a couple. We are, however, dedicated to remaining friends. There will be no further comment."
