When it comes to amazing music videos, Katy Perry does not disappoint, and her latest effort is no exception!

The songstress teased us with a short clip from the video to “Last Friday Night (T.G.I.F.)” last week, and the real thing is finally here! Among many other silly moments, the video for the catchy tune shows Katy getting a makeover from nerdy teen to a sexy siren in a very 80s way.

We all knew that YouTube sensation Rebecca Black was set to make an appearance, but we were pleasantly surprised to see a couple of our favorite faces from Glee as well.

Kevin McHale (aka Artie) makes a cameo as nerd who is majorly crushing on nerd turned bombshell. Also in the video? Sax man Kenny G and the Hanson brothers! Also, in the extended Funny or Die cut, Glee crooner Darren Criss shows up as well. Jeez, who ISN’T in this music video?!
