Billie Joe Armstrong Reveals Which Sports Legend Is A Green Day Superfan

And her joy at a Green Day show in a YouTube clip reminds us why we miss concerts so much!

Armstrong appeared on Jimmy Kimmel Live last night to promote his new memoir project Welcome To My Panic and eventually the subject changed to a mutual friend, Serena Williams. The tennis legend is a Green Day superfan, complete with a favorite throwback deep cut: “Disappearing Boy” from way back on their pre-Dookie debut album 39/Smooth. The chat about Serena starts around the 3:30 mark, but you may want to stick through the first half for some 4/20 talk and audio of Billie Joe singing at just 5 years old.

And if that story wasn’t adorable enough, here’s video of Serena losing her s— during “2,000 Light Years Away” at a Green Day show in 2009. I miss concerts so much I’m tearing up a bit watching this.
