ORIGINAL (4/7/2020): Yesterday Lady Gaga, an entertainer already known for her philanthropy, announced during a call with the World Health Organization that she and an impressive roster of celebrities will participate in a global televised special on April 18 called One World: Together at Home. Featuring the likes of Elton John, Lizzo, Kacey Musgraves, and more, the event aims to "highlight the singular kind global community and celebrate the power of the human spirit."

"We are all so very grateful to all of the healthcare professionals across the country and the world who are on the front lines during COVID-19," said Gaga on the call, according to CBS.

The event comes as a part of Gaga's work with Global Citizen, with whom she has already raised $35 million in just one week according to a note she posted to Twitter. She also noted that the performance will not be a fundraiser and that instead, the raising of funds will happen prior.

"It has been an honor to partner with Global Citizen over the past several weeks as we've been working together behind the scenes to raise money for the World Health Organization COVID19 Solidarity Fund," she wrote. The Solidarity Fund helps ensure essential supplies are available for patients and frontline workers and accelerates efforts to develop vaccines and treatments.

Jimmy Fallon, Jimmy Kimmel, and Stephen Colbert are set to co-host the special. As of now, the musical lineup includes Alanis Morissette, Andrea Bocelli, Billie Eilish, Billie Joe Armstrong, Burna Boy, Chris Martin, Eddie Vedder, Elton John, FINNEAS, Idris and Sabrina Elba, J Balvin, John Legend, Kacey Musgraves, Keith Urban, Lang Lang, Lizzo, Maluma, Paul McCartney, Shah Rukh Khan, and Stevie Wonder.

The live broadcast will begin at 8 p.m. ET on April 18, airing on U.S.-based networks ABC, NBC, ViacomCBS, and iHeartMedia, as well as on Bell Media networks and other Canadian platforms. The next day on April 19, BBC One will run the special along with various international broadcasters.

In addition, the special will also stream on Alibaba, Amazon Prime Video, Apple, Facebook, Instagram, LiveXLive, Tencent, Tencent Music Entertainment Group, TIDAL, TuneIn, Twitch, Twitter, Yahoo, and YouTube.

The effort follows others like it that have seen musicians and performers take their talents online. Last month, Gaga was forced to postpone her album release and cancel a number of live performances.

"Instead I prefer that we spend this time focusing on finding solutions," she wrote at the time. "It's important to me that the attention is on getting essential medical equipment to healthcare professionals, making sure kids who depend on public schools for meals get the assistance they need, and that we help those who will be financially impacted by this pandemic." She's certainly putting those words to action.

"As we honor and support the heroic efforts of community health workers, 'One World: Together at Home' aims to serve as a source of unity and encouragement in the global fight to end COVID-19," said Hugh Evans, co-founder, and CEO of Global Citizen, in a statement. "Through music, entertainment and impact, the global live-cast will celebrate those who risk their own health to safeguard everyone else's."
