Billie Eilish performed as part of the World Health Organisation and Global Citizen’s coronavirus relief concert over the weekend, joining dozens of Aussie and international artists for the eight-hour live stream.

One World: Together At Home raised $128 million for COVID-19 relief efforts, and among the many highlights was when Eilish joined with her brother Finneas to bring a joyous bit of sunshine to her fans and those watching around the world.

“Hey you guys, I chose this song ‘Sunny’ by Bobby Hebb,” Eilish explained. “I chose this song because it’s always warmed my heart and made me feel good, and I wanted to make you feel good.”

Finneas sat at his organ, as his sister gave a heartfelt rendition tune, originally written by Hebb in 1963.

“Sending our love to you and I wanna thank all the healthcare workers risking their lives to save ours. Thank you guys so much,” she said afterwards.

The concert saw other performances by Lady Gaga, Paul McCartney, Green Day’s Billie Joe Armstrong, Delta Goodrem and more.

Among many other highlights, the concert saw The Rolling Stones’ Mick Jagger, Ronnie Wood, Keith Richards and Charlie Watts deliver a socially distanced version of ‘You Can’t Always Get What You Want’.

Eilish had an incredible 2019, taking out a whopping Grammy awards including Album of the Year, Song of the Year, and Record of the Year for her work debut album When We All Fall Asleep, Where Do We Go?

She recently opened up on her struggles with body shaming Instagram trolls, admitting she feels like she “can’t win” against them.

“There were comments like, ‘I don’t like her anymore because as soon as she turns 18 she’s a whore.’ Like, dude. I can’t win. I cannot win,” she said, referring to a recent video she posted of herself on holidays in a swimsuit.
