Here’s your Friday afternoon giggle: Bucks County’s own Justin Guarini donned some leather-licious maroon pants, a shiny silver jacket, and a long head of curls (a la Prince, anyone?) to serenade an office in a Diet Dr. Pepper commercial, and we just love it.

You can check out the entire ad below, and don’t forget to see Guarini, the American Idol alumni, return to Bucks County this summer to play Bobby in Company at Bucks County Playhouse.
