For what might be her most laid-back rendition of "Bad Guy," Billie Eilish performed straight from her childhood home as part of the iHeartRadio Living Room Concert for America on Sunday night (March 29).

During the number, alongside her brother/right-hand producer FINNEAS on guitar, the two lounged comfortably on what's presumable the couch they've had for years to deliver the pop anthem. Instead of Eilish's usual energetic performance of the track, the superstar put her vocals at the forefront as she delicately crooned to the song besides a cabinet of family photos and record vinyls. "We wanted to thank iHeart and FOX for letting us be some sort of comfort in this crazy, crazy time," the pop titan told viewers at the top of the number. "Love to you, your families, your loved ones, everybody. Let's stay strong together. Love you. Take care."

Eilish was one of the many performers to partake in Sunday's concert, which was dedicated to the people risking their lives to fight the COVID-19 pandemic. Earlier this month, the star took to Instagram to remind her 58 million followers of the severity of the issue. "I know we're all scared and worried… we all have our opinions on how to keep each other safe so I don't want to s**t on anybody's whatever but I wanted to really quickly say that it is a really, really big deal right now,” she explained. “It's not a joke. I know because a lot of us haven't seen it with our eyes what it's been doing… it's hard to understand that it's real. But it really is real. And I've seen a lot of young people out in the world... and it's really irresponsible."

You can support two of many charitable organizations that are helping victims and first responders during this difficult time —Feeding America and First Responders Children's Foundation. Every dollar raised from the COVID-19 response fund for Feeding America will be used to get food and funds to local food banks across the US and FOX Entertainment is matching the first $100,000 donated from supporters. Money raised for First Responders Children's Foundation will help support those first responder families who are enduring financial hardship due to the coronavirus outbreak.
