Katy Perry released another music video from her Teenage Dream album. At first I thought that she will release an MV for The One That Got Away, but the next choice was also great! I love the concept of her new video for the single Last Friday Night (TGIF), with all the guest stars and the geeky Katy! Super Lurve this MV! I miss high school! Love to see the Hansons again, now I really miss high school! I also liked that Debbie Gibson's name is Tiffany, haha! Other guest stars are Rebecca Black, Darren Criss, Kevin Mchale, Kenny G. and Corey Feldman. Do you think this is Katy Perry's best music video?
