Lollapalooza is famous for its surprising collabs, but none as shocking as the one captured in a viral TikTok late Sunday.

In it, Blink-182, the pop punk band in the heart of Millennials everywhere, ends their set with a spontaneous cover of Chappell Roan’s “Pink Pony Club.” As lead-singer Tom DeLonge belts out the familiar lyrics, the crowd goes bananas, with one fan singing along in what can only be described as “scream singing.”

It was only a brief interlude, however. After briefly singing the chorus, the band went back into their song “Dammit (Growing Up).” As the song closes, the skies above the stage are covered in celebratory fireworks. The video, uploaded by @lithelibra is at 601,400 views and counting.

Many in the comments claim that this brief homage was manifested by Roan herself, quoting the pop star who once said, “I’m your favorite artist’s favorite artist.”
