For the prank, Perry recreated the concept art of her album, disguising herself as part of an art installation involving a picnic table full of food. According to Vanity Fair, the idea was all hers.
With the stage set, Blasberg invited museum-goers to check out a new “exhibit” by the artist Katherine Hudson (which is Perry’s real name).
As the visitors arrived, Blasberg described the installation before lifting up a tray to unveil Perry’s (totally still) head on the table. Of course, most people assumed they were looking at a mold of Perry’s face — that is until the pop star decided to speak.
“That looks like Katy Perry,” said one visitor, which prompted Perry to respond, “[It’s] Miley Cyrus.”
