It's been just two months since Demi Lovato released a power ballad for "The Mortal Instruments: City of Bones", and already the singer and "X-Factor" judge has a new soundtrack song out, an upbeat version of the song "Let It Go" from Disney's newest animated film, "Frozen."

After a quick social media campaign that urged fans to tweet the track in order to "unlock" it, Lovato released the song on YouTube, tweeting, "Here it is!!!! Listen to my version of #LetItGo from Disney's Frozen!!!"

The full soundtrack for "Frozen" will be released on Nov. 25, according to JustJared, the movie set to hit theaters just days after on Nov. 27.

Disney's newest musical-fantasy is loosely based on Hans Christian Anderson's fairly tale, "The Snow Queen," and tells the tale of two princesses, one of whom is either blessed or cursed with the power to create snow and ice. After her powers get out of hand, she goes into hiding, and the fearless princess Anna (voiced by Kristen Bell) must embark on a journey to find her and save their kingdom.

The original version of "Let It Go" was revealed along with Olaf's song, "In the Summer," at the Disney D23 Expo back in August.

Lovato has yet to comment on her version of the new song, though the singer has been fairly busy lately promoting "The X-Factor" and her upcoming "Neon Lights Tour."

Most recently, she performed three stripped-down piano versions of "Skyscraper," "Nightingale," and her newest single, "Neon Lights" at the Recording Academy for "Live @ The Grammys."

Rumor has it that Lovato's "City of Bones" song, "Heart By Heart," has been submitted by Republic Records for the 2014 Grammys, and her own label, Hollywood Records, has submitted her hit single "Heart Attack" and fourth album for several categories.

"I didn't look at my future and not see music in it," Lovato told the Recording Academy in a recent interview on her early aspirations to become a professional singer. "My work ethic and my desire to create comes from passion. I always have a goal, and I always have a dream. So whether it's creating a song that's going to be a single or an album that I'm most proud of, or a really high note on my album that I really want to be able to sing, or a Grammy one day, or a nomination one day, I don't care, it'd be awesome, I always have passion behind it."
