Ah, the prom 鈥 the (hopefully) fairy-tale climax of what some have called 鈥渢he best four years of our lives.鈥 That was surely the case for the young man who wound up with Kylie Jenner as his date this year, and yet another who gained internet fame with his clever La La Land promposal to Emma Stone, who sadly, had to work (though she did send him a handwritten letter and a boutonniere and corsage in her stead).

It was also surely the case for the young woman who was just promposed to on Jimmy Kimmel Live! with a little help from one Miss Kristen Bell.

While filling in on host duty for the regular late night funnyman on Thursday night, the 36-year-old actress dusted off her Frozen vocal chords to help a high school student named Michael pop the big question to his classmate Sarah.

After sending Sarah on scavenger hunt dubbed 鈥淭he Fast and the Frozenest,鈥 for which she was dressed like Anna (Bell鈥檚 character in the film) and sent out into the streets of LA to find 鈥淜ristoff鈥 in exchange for a prize, Bell let the audience in on the fact that Kristoff was actually the young woman鈥檚 classmate, dressed up to surprise her and ask her for her hand in prom.

Upon their return, Bell instructs Michael to pull off his mask and tell her the truth. 鈥淪arah, there鈥檚 something I wanted to ask you, but I don鈥檛 know the words, so Kristen Bell is going to help me,鈥 he says.

Bell then begins to sing to the tune of 鈥淒o You Want to Build a Snowman,鈥 albeit with a few, erm, lyrical revisions. 鈥淒o you want to be his prom date?鈥 she croons. 鈥淢ichael wants so much for you to go, because if you say no, he鈥檒l have to take his mom.鈥

It鈥檚 not the first time Bell has reprised her role as Anna 鈥 last October, she emulated her own character voice to leave a voicemail for a little girl battling cancer.

With a speechless Sarah eventually saying yes, it looks like she鈥檚 just made one make that two more dreams come true. How sweet!
