Katy Perry has just released the music video for her new single "Last Friday Night (T.G.I.F.) featuring cameos from Kenny G., "Friday" singer Rebecca Black and Glee's Darren Cris and Kevin McHale.

“Last Friday Night (T.G.I.F.)” is Katy Perry‘s fifth single from her third studio album “Teenage Dream.”

In the music video, Perry plays Kathy Beth Terry, a nerdy teenager with braces, headgear and oversized glasses who’s just woken up the morning after a house party, surrounding by passed-out partygoers. A male guest, Aaron Christopherson, (played by Glee star Darren Criss) opens the door to her bedroom and congratulates her on having the best party ever. Puzzled as to what happened, she goes online, only to find pictures of herself in various compromising positions. The video then goes into a flashback of the events that occurred the night before. While playing Sudoku puzzles, Kathy hears loud music from the house next door, and goes over to stop the commotion. She is greeted by the hostess (played by Rebecca Black), who invites her to come in. Another nerdy high schooler, Everett McDonald, played by Glee star Kevin McHale, ogles her from afar and fantasizes about being with her. Kathy, however is more interested in Steve Johnson, the attractive football player attending the party, who turns her down because of her appearance. To cheer her up, Black gives Kathy a makeover, ripping off her headgear with pliers, dressing her in tight-fitting neon clothes and teasing her hair out. Steve becomes enamored with her, and everyone starts dancing. Jazz musician Kenny G plays a saxophone solo on the roof while 90s heartthrobs Hanson act as the house band. The entire party ends up moving to Kathy’s house, where Everett punches Steve for fondling Kathy. At the end of the night, Kathy finally passes out next to Steve. The video shifts to present day, where she looks on with regret, but is also ecstatic to have a naked Steve passed out in her bed. During the video’s end credits, there is a follow-up scene, where Everett makes breakfast in bed for Kathy. Also, there are additional scenes from the party and bloopers. Former teen idols Corey Feldman and Debbie Gibson make a cameo as Kathy’s parents Kirk and Tiffany Terry.
