We all know Katy Perry now as a confident rock star, but apparently there was a time when she wasn’t as cool as she is now.

A teaser for the singer’s latest video for “Last Friday Night (T.G.I.F.)” has been released and she gets geek chic in some braces and headgear, in addition to some awesomely 80s gear.

And is it just us, or does it seem like this song was inspired by The Hangover?

With lyrics like “there’s a stranger in my bed,” and “it was a blacked out blur” we can’t help but think of the hit comedy when we listen to the catchy tune. Take a listen for yourself below, then watch the teaser above!
