Sia and husband Erik Anders Lang are separating after two years of marriage, People reports. The couple released a statement to the publication, saying, "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." While the pair mostly kept their relationship quiet, they wed back in August 2014 and their last public appearance together was at a Spotify party in LA back in February.
