“Hello, to all of the families across the world, I’m very proud and honored to be a part of the Disney family,” Beyoncé, who voiced Nala in the live-action remake of Disney’s The Lion King, began.

She then dedicated her virtual performance on the special, which was done in partnership with Feeding America and hosted by Ryan Seacrest, to the health care workers, who are risking their lives to fight the spread of the coronavirus (COVID-19) pandemic.

“I’d like to dedicate this song to all of the health care workers who have been working tirelessly to keep us healthy and safe. We greatly appreciate you,” Beyonce said before crooning a rendition of “When You Wish Upon a Star” from the Disney classic movie Pinocchio.

Wearing hoop earrings with her hair styled in tight curls, Beyoncé softly belted out the iconic lyrics: “When you wish upon a star / Makes no difference who you are / Anything your heart desires will come to you.”

Beyoncé concluded the tune, telling fans, “Please hold onto your families tight. Be safe, don’t give up. We’re going to get through this, I promise. God bless you.”

Beyoncé’s appearance came as quite a shock as she was not announced on the lineup ABC provided ahead of time.

Her performance prompted excited reactions on Twitter, with journalist Austin Kellerman tweeting, “LISTEN: Beyonce performs ‘When You Wish Upon a Star’ and dedicates the song to health care workers. Just Perfect.”

“Beyoncé!!!!! And Disney I cannot!!!” another fan wrote.

“Beyoncé promised us that we’re gonna get thru this. I believe her,” singer Jessie Woo tweeted.

“BEYONCÉ HAS BLESSED US!!” another fan said.
