Channeling her nerdy alter ego Kathy Beth Terry, Katy Perry has a wild party in "Last Friday Night (T.G.I.F.)" music video. Originally planning to spend the night on her bed, Kathy is corrupted by Rebecca Black when coming over to her home to confront her regarding some noise. The geeky girl is persuaded by the YouTube sensation to enjoy the home party instead.
The morning after, Kathy wakes up in her own bed next to a shirtless guy but doesn't remember a thing. "There's a stranger in my bed/ There's a pounding my head/ Glitter all over the room/ Pink flamingos in the pool/ I smell like a minibar/ DJ's passed out in the yard/ Barbie's on the barbeque/ There's a hickie or a bruise/ Pictures of last night ended up online, I'm screwed," she sings.
"Glee" actor Kevin McHale portrays a nerdy boy who becomes Kathy's knight in shining armor. Another "Glee" star Darren Criss also makes a cameo as another boy who is left impressed by her after the wild gathering. Kenny G and Hanson help keep the crowd going with their music. Corey Feldman and Debbie Gibson are the cool mum and dad.
"Last Friday Night (T.G.I.F.)" is taken from Katy Perry's 2010 summer studio album "Teenage Dream".
