The 48-year-old singer debuted "Recovering" on Thursday, which was written by Pink. The emotional lyrics talk about putting your life back together after going through a difficult time. "Little by little, day by day/ One step at a time," Dion sings. "Shake off the devil/ Take back my piece of mind/ I am recovering."
When ET spoke to Dion back in July about the song, she told her fans to "get ready."
"[Pink] is phenomenal. I love her for her talent, for her strength, for her focus, the person she is," she gushed over the 37-year-old singer. "At the [Billboard Music Awards] when I saw her, I said, 'For you to take the time to really write a song, to give me a tool, a piece of luggage to help me to move forward to walk to keep going…'"
"Recovering" is the first single off Dion's upcoming album. She has not released an English-language album since 2013's Loved Me Back to Life, which featured Sia -- who she recently impersonated on The Tonight Show -- and Ne-Yo.
As far as performances go, Dion is set to sing at Friday's Stand Up to Cancer live TV event and on The Ellen DeGeneres Show on Monday.
