Kristen Bell Helps Teen with 'Frozen'-Themed Promposal! (Video)

Kristen Bell helps a high school teen prompose to his crush while guest hosting an episode of Jimmy Kimmel Live on Thursday (May 4) in Hollywood!

The actress called two girls out of the audience and dressed them up in Frozen costumes and told them whichever one found a man dressed up as Kristoff on Hollywood Boulevard first would win a prize. It was all a set-up though and one of the girls was actually an actress who wasn’t competing at all.

Sarah, the real contestant, found Kristoff and brought him back into the studio. When he took off the mask, he was revealed to be her high school classmate Michael, who had Kristen ask Sarah to prom for him in the tune of “Do You Wanna Build a Snowman?”
