The Smashing Pumpkins and Marilyn Manson's co-headlining tour recently came to an end, but the people of Nashville, Tenn., got an extra surprise during the tour's final stop. During Manson's set, Smashing Pumpkins frontman Billy Corgan came onstage dressed as a nun to sing on "Antichrist Superstar" and a cover of Cyndi Lauper's "Girls Just Wanna Have Fun."

The massive tour brought together two acts who ruled the rock scene in the '90s and continue writing great music to this very day. Billy Corgan mentioned at a June press conference that he and Manson planned to cover the Cyndi Lauper pop classic, and Nashville was the city to see it happen.

Manson was performing "Antichrist Superstar" from his signature podium before Corgan surprised the crowd in his nun outfit. The duo performed a portion of the song together, seamlessly blending "Girls Just Want to Have Fun" into the tail end of "Antichrist." The result was a creepy as hell, but Marilyn Manson is well versed in turning pop into gothic darkness.
