Larry Busacca/LP5/Getty Images for TASImagine Dragons' Dan Reynolds joined Taylor Swift onstage Saturday night when the pop superstar performed at Detroit's Ford Field.
Swift's tours often feature surprise appearances by big-name guest stars. On Saturday night, she introduced Reynolds by calling ID one of her favorite bands, and then the two performed what she described as one of her favorite songs: the massive hit "Radioactive." Afterwards, Taylor tweeted, "Thank you again @DanReynolds for coming to Detroit. You're incredible."
Dan, for his part, tweeted, "thanks for having me @taylorswift13 u are a gem of the rarest kind - like found in stalagmites in the earths core next to t rex bones."
Imagine Dragons' own tour starts Wednesday in Portland, Oregon.
