We hope you're up for a game of "I Spy Katy Perry's semi."
The 28-year-old pop star has wheeled out an impressive - and shiny - promotional campaign for her upcoming album.
Instead of using a regular old billboard, the singer has deployed a golden semi-truck bearing the details - "Katy Perry – Prism – 10.22.2013" - on its side.
"Find the #PRISM semi, take a picture and I'll RT you," she encouraged her Twitter followers on Monday. "Don't worry, Los Angeles is just the first stop on the map."
Perry's played coy about what exactly is rolling down the highway in her "Prism" truck, but she hasn't been as shy about her progress on the record. Back in April, she told Billboard that she was halfway done with the follow-up to 2010's chart-topping "Teenage Dream," which boasts five Hot 100 No. 1 singles.
With that much success, it makes sense that she would once again collaborate with some of the same names from "Dream," including Max Martin, Dr. Luke, Bonnie McKee and Greg Wells.
