It look like Katy Perry is getting her '80s on in the goofy video for her new single "Last Friday Night" that will officially premiere on June 24. The teen pop queen turns into her alter-ego Kathy Beth Terry, and timewarps back to her high school days for a little fun. And Katy wouldn't be Katy (or Kathy) if she didn't sprinkle some of her bubblegum goodness across the final product. Looks like a good time and note that little nod to Hanson. Watch the trailer after the break.
