Kathy Beth Terry, a.k.a. Katy Perry, stars in the official music video for "Last Friday Night (T.G.I.F.)," a work that actually lives up to its significant hype.
Featuring Rebecca Black, Darren Criss, Kevin McHale, Hanson, Kenny G, Debbie Gibson and Corey Feldman, this is more than an average music video.
An eight-minute short film would be more accurate, with KP and her many outfit changes paying homage to all things geeky, '80s and '90s.
