This Diet Dr. Pepper commercial might cause you to do a double-take.
At first glance, it's just your normal soda ad that features a few employees in the work break room looking for a sweet pick-me-up, and one special lady's carbonated desire happened to summon Lil' Sweet, who—surprise!—ends up being Justin Guarini!
All of a sudden, a little man slides into the room on his knees, dressed in a red wig and shiny metallic pants and hands her a Diet Dr Pepper. If you take a closer look, take away the garb and eyeliner, you'll realize it's the American Idol alum. Well, that, and it also says his name down on the bottom.
He starts showing off his killer vocals by hitting some ultra-high notes about the sweetness of Diet Dr. Pepper before explaining that he does not work with the employees in that break room (he's self-employeed) and then slides back out on his knees.
