"We're bringing attention to the importance of supporting local communities as well as the local charities," Usher said Friday on "Good Morning America," "and also to recognize those who are actually doing the work and bringing relief through entertainment and communication and sharing specific stories."

The special isn't a telethon -- it's described as a "global broad entertainment special to celebrate the heroic efforts of community health workers and support the World Health Organization and the global fight to end COVID-19."

In addition, the special's stated purpose is to "educate and inform on COVID-19 risks, prevention and response," so in addition to the stars, WHO experts and healthcare workers will appear.

Other platforms where you can watch or stream the show include Bravo, E!, Freeform, MTV, CMT, Comedy Central, VH1, SYFY, MSNBC, Facebook, Hulu, Instagram, Apple, YouTube and Yahoo.
