A bodacious new video from Katy Perry has arrived.

In 'Last Friday Night (TGIF),' a neon-hued sendup of every 1980's party scene you've ever seen, the pop star wears nerdy braces and retro fashions in her wildly optimistic ode to, well, not love so much as...a love of binge drinking.

Perry's booze-laced fantasies are also laced with gnarly celebrity cameos -- from Hanson jamming in the backyard, to Kenny G's super sax-y rooftop solo, to pivotal roles played by 'Friday' singer Rebecca Black and 'Glee' star Kevin McHale. Check out the full video after the jump.
