Billie Eilish just brightened up fans' quarantine days with a beautiful cover of Bobby Hebb's soul classic “Sunny" from her LA home, as part of Global Citizen's Together at Home initiative.

Global Citizen launched the One World: Together at Home campaign to support frontline health workers and the World Health Organization during the Covid-19 pandemic. As part of this campaign, numerous artists including Stevie Wonder and Taylor Swift, broadcast performances from their homes.

This weekend, Billie and her brother, Finneas, became the latest artists to join the movement. With Finneas on the keys, the singer gave a soulful rendition of the popular song, giving new life to the recognizable lyrics, "Sunny, yesterday my life was filled with rain / Sunny, you smiled at me and really eased the pain."

Watch her adorable performance below.
