Billie Eilish [1] took home song of the year for "Bad Guy [2]" at the Grammys on Sunday night. During her acceptance speech for the award, the 18-year-old — who also won best pop vocal album [3] for When We All Fall Asleep, Where Do We Go? — took a moment to reflect on the special honour. "I feel like I joke around a lot and I never take anything seriously at these kind of things, but I genuinely want to say I'm so grateful," she said before the passing the mic to her brother and best friend, Finneas O'Connell. He then gave a shoutout all the aspiring musicians who are currently writing music in their bedrooms. "You're gonna get one of these," he said, holding up his Grammy. Watch their cute speech ahead.
