Taylor Swift continued her 1989 World Tour with another guest star in Indianapolis when The Band Perry joined her on stage.

Swift sang the hit song “If I Die Young” and posted a clip to Twitter and Instagram. The band was also excited to be there, calling it a “magical night.”

They weren’t the only stars in attendance, though. The Fault In Our Stars author John Green broke his recent “no social media” rule to reveal that he was in the audience, too.

The Band Perry joins a trove of other celebs who’ve joined Swift on her world tour, including Wiz Khalifa, Justin Timberlake, Julia Roberts, John Legend and many more.
