Sia took over the iHeartRadio Twitter account for our #TwitterTuesday Takeover, where she answered questions from her fans from all over the world. 

Sia is getting ready to release her new album This Is Acting on January 29th, which is the follow-up to 2014's 1000 Forms of Fear and includes songs that she's written for other people who didn't end up using them - hence the album title This Is Acting. This Is Acting includes her single "Alive."
