If you need of a little pick-me-up today, look no further than Millie Bobby Brown and Sadie Sink's performance of "For the First Time in Forever" from Disney's Frozen [1]. On Thursday, Brown posted a behind-the-scenes clip [2] of the Stranger Things [3] costars — who were working on set of the Netflix series at the time — channelling Elsa and Anna from the 2013 flick. While Brown played Elsa, Sadie assumed the role of Anna as they showed off their insanely impressive vocals. I mean, if Disney ever wanted to recast the characters' voices, we're throwing Brown and Sink's hats into the ring.

Both actresses have shown off their musical skills before. In May, Brown sang an amazing rendition of Amy Winehouse's "You Know I'm No Good" [4] on The Tonight Show Starring Jimmy Fallon [5] and has previously joined Maroon 5 on stage [6] to rap Cardi B's part of "Girl Like You." And who can forget when she nailed Nicki Minaj's "Monster" verse [7]? Meanwhile, Sink has appeared on Broadway in Annie and The Audience. No wonder they make that Frozen performance look so effortless!
