Winter is near, but Demi Lovato isn't scared at all. On the just-released "Let It Go," off Disney's upcoming animated film "Frozen," she's reaffirming that "the cold never bothered me anyway."

When she firsts paints the picture of snow-covered mountain with "not a footprint to be seen," you may think she's taking us on a walk in a winter wonderland. But when she warns that "the wind is howling like the swirling storm inside," it's clear that this is a snowstorm inside and out.

But clearly this storm had never met Demi, had never heard one of her impenetrable ballads. The track is about a woman who can stand up to just about anything -- even the harshest of blizzards -- because "the fears that once controlled me can't get to me at all." It's an appropriate message for "Frozen." When MTV News caught up with Kristen Bell, who lends her voice alongside Idina Menzel, she told us conquering fear is the main message.

"The movie is about a pair of sisters -- one who has the power to freeze things, and it happens when she is fearful or angry," Bell said. "And because of feeling terrified to show that to the world, she sort of runs away and freezes the town accidentally. I play the sister Anna, who makes it her mission to travel across these snowy lands and bring her sister back amidst the fact that they're fighting and kind of at that point hate each other. It's kind of how they make up and find love in the end."

"Frozen" hits theaters November 27. And later this winter, Lovato will embark on her Neon Lights Tour.
