For Heidi Klum, the best part of Harvey's performance was "how raw and how real and how honest" the whole thing felt.
"There was no backing track, there was no production around it. It was just you, your beautiful voice, your ukulele, and it was very powerful," she shared.
Mel B was equally effusive with her reaction, praising the singer for her impact and her influence on others who look to Harvey as an inspiration. "You make the impossible, possible," the former Spice Girls star said. "You're like a miracle worker, and you've literally taken me on an emotional journey."
