"This year I wrote him a text, and I said, 'Hey, listen, you're like one of five people that I'm sexually attracted to, and now that I've decided to be single for the rest of my life and I just adopted a son, I don't have time for a relationship ...

Sia is set to debut a new single, titled Together, in the coming hours. It will serve as the first single from her upcoming film Music, starring Ziegler, Kate Hudson and Leslie Odom Jr.
