The Pitch Perfect star sang Poor Unfortunate Souls and was joined onstage by other Hollywood stars who covered different songs from the Disney flick.

Rebel (Ursula), John Stamos (Chef Louie), Tituss Burgess (Sebastian), and Sara Bareilles (Ariel) were accompanied by a full, live orchestra onstage and, quite frankly, our FOMO is through the roof.

"Sooooo much fun working with this incredible cast! And singing such incredible material! Thanks Norm, Josh, Darren, Sara, Sandy, Titus and John and thanks Alan Menken for being such a lovely genius," the 36-year-old wrote on Instagram.
