Star Spotting: Is Katy Perry Turning Into Mary Katherine Gallagher? (VIDEO)

Katy Perry may or may not be turning into Mary Catherine Gallagher

Katy Perry channeled her inner-Mary Katherine Gallagher last night on “Fallon.”

Katy Perry is usually the very picture of grace and serenity, no? Just look to her angelic Billboard cover, where she’s drenched in golden sunlight and surrounded by butterflies.

And then there are the other times… times when Katy ditches the butterfly bullsh** and gets real. Which, in Katy Perry Land, means channeling Molly Shannon’s “SNL” character and not-so-repressed Catholic schoolgirl, Mary Katherine Gallagher, on “Late Night With Jimmy Fallon”! Because pleated skirts, pigtails, and knee-highs!! And smelly armpits! (Although we’re pretty sure Katy’s incapable of B.O. — heck, for all we know, her pits smell like freshly baked cronuts.)

Watch Katy Perry on “Jimmy Fallon” after the jump.

Anyway, it wasn’t just Katy’s dead-on MKG ensemble that made us wanna be all “SUPAHSTAH!!!” We were also LOL-ing our faces off over those nerdy, awkward “Last Friday Night (T.G.I.F.)” faces Katy kept making while playing a game of Taboo with Jimmy! That’s Katy for you: never afraid to be a gorgeous goofball.

Alternately, maybe we misinterpreted Katy’s entire shtick. Perhaps she rocked that leather, pleated, “Dark Horse“-inspired skirt to pay homage to Britney Spears‘ schoolgirl look circa “Baby One More Time“? I mean, gotta keep the crowd guessing now that she’s burned all of her wigs and chucked all of those candy-themed onesies!

Either way, we commend Katy for having enough chutzpah to rock pigtails AND knee-high socks after the age of 14. NEVER LOOK BACK, KATY! (Except for when standing in front of folding chairs, of course.)
