Kristen Bell took over the hosting duties on Jimmy Kimmel Live! last night and created a magical promposal for an unsuspecting high school girl.
The star of Disney's Frozen called a couple of audience members to the stage for a chance to win some Frozen-themed prizes, but she was really just trying to help a student named Michael ask his friend Sarah to the prom. Bell had both girls from the audience dress like Anna and Elsa and sent them out on the street in search of someone in a Kristoff costume. The first one to find him would win a prize.
Sarah found Kristoff and brought him back to the theater, at which point he took off his costume head to reveal that he is Michael. Bell then sang a re-worded version of "Do You Want to Build a Snowman" to ask Sarah to the prom. Sarah said yes.
