Katy Perry's "Last Friday Night". ( video )

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.
Perry starts out in her bedroom as a bespectacled spaz experiencing some seriously technicolor morning-after flashbacks: Who gave her a hickey? Why does she smell like a mini-bar? Is that really her doing body-shots in party photos? It's all a blur, or perhaps a dream.

Neil Patrick Harris will Host 2011 Tony Awards.

Neil Patrick Harris has officially been named host of the 2011 Tony Awards and if all goes well, he'll be flying high once the curtain goes up -- literally.

"Since they're closed for retooling, we're using all the rigging equipment from 'Spider-Man.' What could possibly go wrong," Harris joked in a press release.

Although this will be Harris' second go at the Tony hosting gig -- he hosted the show to rave reviews in 2009 -- we can't imagine that his none-newbie status takes off any of the pressure to perform.

"I'm honored and stoked to have been asked to host the 2011 Tony Awards," he said. "It should be a great show -- we've got a fantastic mix of live performances [and] a few secret surprises."
