"One World: Together At Home" is a star-studded charity event with a lineup curated by Lady Gaga. The concert, which is raising money for the COVID-19 Solidarity Response Fund and is supported by the World Health Organization and Global Citizen, will be broadcast on Saturday starting at 8 p.m. ET, and also has a digital livestream with pre-show acts that's been available on Global Citizen's social media accounts since 2 p.m. ET.

Ahead of the live broadcast, Lady Gaga opened up to her fans and followers in a live Instagram video. "I'm so grateful for the healthcare workers, the medical workers, all the grocery store workers and delivery people, the postal workers, all the other nonprofits that are working so hard," Lady Gaga said through tears in the video.
