Katy Perry Debuts "Last Friday Night (T.G.I.F.)"

Getting into character as her nerdy alter ego, Katy Perry transformed herself into Kathy Beth Terry by Rebecca Black for the wackiest new video accompanying her latest single, "Last Friday Night (T.G.I.F.)" the fifth single off Perry's 2010 album "Teenage Dream," and it's easily her best yet, and she included a couple of random pop-culture phenomenons just for the fun of it. The pop star ends up turning into a '80s glam party animal in her wildly optimistic ode to a love of binge drinking, is proving to be as adept at comedy as her husband, edgy British comic Russell Brand.
Perry explained that this mid-tempo party anthem, which recalls all the fun nights gone by, had a purpose for being on the album: "There's a lot of substance, but also some no-brainers," she said. Perry added that she likens the tune to "I Gotta Feelin'" by the Black Eyes Peas. Perry was inspired to write this track after running naked through a park. She explained: "There's nothing better than an impromptu dance party with my friends. My track 'Last Friday Night (T.G.I.F.)' is a song about debauchery because I had one of those nights in Santa Barbara. We went out to this place called Wildcat and got crazy."
The 26-year-old added that despite drawing from her own experiences in the tune, the raunchy threesome mentioned in the track didn't actually happen. She admitted: "We had a couple of beers and danced until we died, then brought the party back to the hotel room. Most of that song is actual truth, apart from the ménage à trois... unfortunately! But, yes, streaking in the park, that's what we did, so we had to write a song about it the next day!" The whole thing is one big late '80s-early '90s fun throwback that most of us can likely relate to at one point in our lives or another.
The new video was produced by Dr.Luke and is truly a classic Perry video among fun, entertaining and humorous. In video, Perry takes on an '80s nerdy side as she wakes up in her bed wearing braces, a turtleneck and taped glasses after a (Friday) night of hard partying to find a bunch of strangers passed out in her room, her house a mess, and worst of all as embarrassing pictures of her posted on the internet. At first, it seems like just about every teenager's worst nightmare until Perry realizes that she's just had the greatest night of her life.
