This summer, Diet Pepsi teamed up with actor Josh Duhamel to surprise Diet Pepsi fans in stores. The actor posed as a store clerk, scouring aisles, parking lotsJosh Duhamel for Diet Pepsi and register lines to give Diet Pepsi fans an unexpected break in their grocery store routines. The brand later released a video from a hidden camera in the store that recorded fans having fun with Duhamel. “I had a blast ‘checking out’ Diet Pepsi fans at the cash register — it was like hosting my own candid camera!” Duhamel joked in a statement.

 “Seeing the surprised reactions in real-time was really fun, and I hope we gave a lot of shoppers a great story to tell their friends and family.”
