Superstars Menzel and Bell will perform "When We're Together" from the brand-new Walt Disney Animation Studios featurette, "Olaf's Frozen Adventure."

"This performance will combine two of my very favorite things: the holidays and singing alongside my 'Frozen' sister, Idina Menzel," said Bell. "I'm excited to sing a song with Idina that I feel has the potential to become a new holiday classic."

Said Menzel: "Anytime I get to reunite with Kristen, whether it's in the studio or on the stage, is very special for me. I think I can speak for her when I say we are both so proud of this story we get to tell and these sisters we get to portray."
