Katy Perry released her fifth single from her third studio album Teenage Dream, known as Last Friday Night (T.G.I.F.), featuring internet celebrity Rebecca Black in a cameo.

Soon after its release, Last Friday Night (T.G.I.F.) peaked at number sixty-three on the Billboard Hot 100 and number forty-nine on the Canadian Hot 100 because of digital sales.

The song was written by Perry, Dr. Luke, Max Martin and Bonnie McKee, and was produced by Dr. Luke and Max Martin.

The music video for Last Friday Night (T.G.I.F.) was filmed in May 2011. It was directed by Marc Klasfeld.

In the video, Perry plays Kathy Beth Terry, a nerdy teenager with braces, headgear and oversized glasses who just woke 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, Katy hears loud music from the house next door, and goes over to stop the commotion. She is greeted by the hostess, played by internet celebrity 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. Katy, 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 charmed 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 Katy's house, where Everett punches Steve for fondling Katy. At the end of the night, Katy 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.
