"I just want you to know that this is really a true love letter to all of you all over the world, and I hope a reminder of the kindness that's occurring right now. You're all so special, and the world is a special place, and we're all together at home, and we're one world," she continued.

"I hope that you feel a big hug from the whole world today because what's really beautiful about this show is that you're all hugging each other, and it's something that everyone always wanted it to be," the artist said.

Lady Gaga ended the video, saying: "I don't know how to say this any other way but ever since I was a little girl, I always wanted to make people happy, and I didn't know why, but I think I know today."

The musician spoke about the charity event at a Friday press call hosted by the WHO, calling the concert a "love letter to our doctors" and all essential workers.

"During this time, we have seen the coming together of a singular, kind, global community," Gaga said. "I'm Lady Gaga. I'm an Italian-American patriot, but I'm also a global citizen."
