Demi Lovato is back -- by the skin of their teeth.

The 29-year-old singer, who identifies as they/them, dropped their new single "Skin Of My Teeth" on Friday with a video.

Over a background of drums and guitar, the artist openly references their previous drug struggles and mental health. "Demi leaves rehab again / When is this s*** gonna end? / Sounds like the voice in my head / I can't believe I'm not dead," they powerfully open the song.
