Kristen Bell - Kristen Bell Felt Chills Singing With Idina Menzel

The Forgetting Sarah Marshall star voices the role of a young girl searching for the Snow Queen, portrayed by Menzel, in the forthcoming musical film Frozen, and Bell admits singing with the stage superstar was awe-inspiring.

She tells Eonline.com, "It's just unbelievable. It's bone-chilling is what it is - bone-chilling!"

And Bell reveals lending her voice to Frozen helped her achieve a lifelong goal: "It's quite literally my dream come true because I've been obsessed with Disney princesses since I was a little girl, as most little girls are. I studied music in college, so this is a very, very real dream for me coming true."
