Kelly Clarkson releases 'Piece by Piece (Idol Version)'; remix album to follow
American Idol

Even though Kelly Clarkson is pregnant with baby number two, she's still keeping her name in the public. On Feb. 25, she went back home to "American Idol" to not only perform but be a guest judge. After offering her wise advice to the newly named top 10, she took the stage to perform the acoustic version of latest single "Piece by Piece" as performed on tour in 2015. Emotionally slaying the audience as well as the judges, she too couldn't hold back the tears while pulling the heartstrings of millions of viewers. The performance sent the radio remix of the single straight to No. 1 on iTunes where it has remained. Now, today (Feb. 29), she has released the acoustic "Piece by Piece" after recording a studio version. It's all but perfect timing following a moment that will go down in "Idol" history as she gave her last performance on that series.

"Piece by Piece (Idol Version)" can now be purchased featuring that beautiful piano played by lifetime musical director Jason Halbert. Clarkson thankfully had the convenience of recording in studio in case she was unable to keep herself together. There's still tender moments in her voice that pull you in and break your heart. That's not all.

Also, on Friday, March 4, Kelly Clarkson will released her first ever remix album, Piece by Piece Remixed. It will feature remixes of songs from the album including lead single "Heartbeat Song" and follow-up "Invincible." Along with the new acoustic version of the title track, it will include the tour version of album track "Tightrope." Performing it live Clarkson took the song down in pitch so she could wail in various parts of the song, taking its lyrics of uncertainty in a relationship to a new level.

The "Idol" finale is to take place around the same time Clarkson is due to have her baby boy with husband Brandon Blackstock. A medley was taped prior to Thursday's show (Feb. 24) as she's not allowed to fly from now till delivery.

Later this year, Clarkson will also release her first children's book inspired by her daughter River Rose, aptly titled "River Rose and the Magical Lullaby." The book is set to arrive on Oct. 4, 2016.
