While many stars opted for casual wear to give their at-home numbers, Halsey went full-on Ariel in a beachy sundress and a red wig accessorized with a pearl-studded hair clip.
Just hours before her appearance, she teased the look with a couple of photos on Instagram.
True to form, Halsey’s rendition of the classic was note-perfect and made a splash with fans on social media.
Some people went so far as to suggest that Halsey replace Halle Bailey in the forthcoming live-action adaptation of “The Little Mermaid.”
The show also gave Bailey, who is one-half of the R&B duo Chloe x Halle, an opportunity to let her talents shine. She joined her sister, Chloe, and Anika Noni Rose on a rendition of “Almost There” from 2009’s “The Princess and the Frog.”
In February, Halsey kicked off a European tour in support of her third album, “Manic.” The U.S. leg of the tour, originally slated to begin in Seattle next month, has been rescheduled to 2021 due to the coronavirus crisis.
