Last Friday Night (T.G.I.F.) is a dance‑pop single recorded by American singer Katy Perry. Issued as the fifth single from her third studio album, Teenage Dream, the track was released in June 2011 and quickly became one of Perry’s signature party anthems. Its title and chorus play on the popular expression “Thank God It’s Friday,” while the lyrics describe a comically chaotic night of youthful excess and the hazy aftermath.
Composition and themes
The song is built around glossy synths, a propulsive beat and a memorable singalong hook, placing it firmly in the mainstream pop and electropop styles that dominated early 2010s radio. Lyrically, it adopts a light, tongue‑in‑cheek tone, recounting incidents from a rowdy weekend with self‑aware humor rather than moralizing. Perry’s vocal delivery mixes conversational verses with an emphatic, melodic chorus designed for mass singalongs.
Release, remixes and video
Released on June 6, 2011, the single was later reworked in a remix that featured rapper Missy Elliott, broadening its appeal in clubs and on urban radio formats. The official music video presents a retro teen‑movie narrative in which Perry plays an exaggerated nerdy character who undergoes a dramatic makeover; it also includes cameo appearances by various entertainers and briefly references a viral pop moment, creating a vivid visual counterpart to the song’s party story.
Chart performance and records
Commercially, the song reached number one on the US Billboard Hot 100 and achieved top positions in several other countries, including Canada, while placing within the upper reaches of the charts in Australia, New Zealand, the United Kingdom and parts of Europe. Its success made it the fifth number‑one single from the same album, a milestone that marked Perry as the first female artist to reach that tally; prior to her, only Michael Jackson had collected five chart‑toppers from one album.
Reception and legacy
Critics generally appreciated the song’s catchy construction and its embrace of unabashed pop frivolity, though some noted that its subject matter was deliberately trivial. Over time it has remained a staple of contemporary pop playlists, radio rotations and Perry’s live shows. The single also contributed to the broader cultural narrative around Teenage Dream as a commercially dominant pop album of its era.
