At one point during the set, Billie fell flat on her face and joked with the crowd that she just "ate s***!" The stage had just gone dark when she fell, so fans could hear it but they didn't see it. She groaned, "Ouch! You guys, I just ate ass up here!"
Sounds like it did hurt ... Billie later repeated, "Ow," as she held her hand as if it was causing pain. She added, "You guys, I seriously ate s***. Seriously. It was pitch black. You see that square?: This f***ing thing? I went de-de-de-de-de and fell onto my face!"
Billie was undeterred, saying "I'm good. It was dark. Ouch, I tripped on the f***ing fire thing."
