What’s better than one Katy Perry song? Well, a whole bunch of them mashed together equals one epic track. “Tommie Sunshine’s Megasix Smash-Up” encapsulates Perry’s cupcake-bra-wearing, blue hair, braceface, extra-terrestrial, GI Jane aura.

The DJ took all her hits from the past 18 months and mixed them together in seven minutes. Included is: “Teenage Dream,” “California Gurls,” “Firework,” “The One That Got Away,” “Last Friday Night (TGIF),” and “E.T.”

The track will be included on Perry’s album Teenage Dream: The Complete Confection, which comes out today. [Source]

Katy Perry has released a video teaser for her upcoming single ‘Last Friday Night.’

Along with a new song, Perry is also sporting a rather new look. Geek chic? Let’s just say it’s far from her fashion-forward Elle cover.

This marks Perry’s fourth single off her latest album ‘Teenage Dream.’ The video drops June 14th.

Also, thanks to a savvy YouTube commenter, I believe one can spot Rebecca Black (Friday, Friday, Gettin’ Down On Friday) at exactly 0:15 seconds. I wonder what her part will be in this!

Check it out the craziness below!
