Billie Eilish, the coolest teen on the planet, just became even cooler after making her televised awards-show performance debut at the AMAs with a fiery performance of her hit single “All the Good Girls Go to Hell.†She also picked up two statues, one for Favorite Alternative Rock Artist and the other for New Artist of the Year. You’d probably be geeking out if you won multiple major music awards at the age of 17, but Eilish was chill as ever, hugging Post Malone, enjoying a lollipop with Dua Lipa, and even introducing the band fronted by a fellow alternative Billie — Billie Joe Armstrong — for the 25th anniversary of Green Day album Dookie. The coolest part? Eilish rocked a shirt that said “No Music On A Dead Planet,†so the Billie Eilish x Greta Thunberg x Jane Fonda collab will hopefully be dropping any day now.
