Kelly Clarkson is only a few days away from releasing her comeback album "Piece by Piece". To build the anticipation, the former "American Idol" winner premiered on Monday, February 23 a new track called "Invincible".

The track highlights Clarkson's powerful vocals as she sings inspiring lyrics about growing up and becoming a stronger woman. "I was so afraid, I felt so unsure/Now I am invincible, another perfect storm," she coos.

"Invincible" was penned by Australian singer/songwriter Sia Furler. It's been confirmed as track No. 2 on "Piece by Piece", which is coming out on March 3. Along with the forthcoming LP's lead single "Heartbeat Song", the track is available as free download for fans who pre-order the follow-up to 2011's "Stronger".

Clarkson recently revealed why she only had John Legend on her list of collaborators for her new full-length. The mother of one said in an interview with BBC Radio 1 that she had trouble finding musicians who wanted to work with her.

"I honestly would collaborate with a lot of people, but everyone usually says no," she said. "I'm not kidding you. I have legitimately asked several people that I'm not going to call out, and that's cool, but I don't know."

"I ask good people, I don't want to sing with crap people, so I mean, I ask people who are great vocalists, but I'm not going to point out anyone. I have asked several people... Sometimes I feel like I have the plague, or leprosy, they're like, 'If you get too close.' I don't know," she continued.

Of getting Legend for one of her new songs, she added, "I'm gonna keep John Legend. He's super credible and talented. I feel very good about myself with that one."
