Songstress Demi Lovato has finally premiered the music video for her new track 'Let It Go', which features on the soundtrack for the upcoming Disney movie, 'Frozen'. 

The film is about a young woman searching for her sister and while Idina Menzel performs the version of 'Let It Go' that features in one of the scenes, Lovato recorded vocals for the soundtrack edition. 

Her music video for the emotional song shows footage from the motion picture as well as scenes of Lovato singing the lyrics in a dark old house (pictured below). 

Meanwhile, the beauty is gearing up to release her first book, 'Staying Strong', which she explained is an inspirational guide that she hopes fans will find useful: "I will be releasing a book called 'Staying Strong'. One thing that's helped me with my recovery is taking every day one day at a time. I'm a firm believer in starting off the day the right way with an inspirational quote and a morning meditation."

'Staying Strong' will debut on November 19 and the animated film 'Frozen' will premiere on November 27.
