Britney Spears has official entered the halls of William McKinley High School—and we have the photographic evidence to prove it.

Earlier today, the pop princess got Gleeks everywhere excited when she revealed her location. “About to do my first shot of the day for Glee tweeties! Here we goooo!” she tweeted.

She later provided her own photo taken from the set (with her assistant Brett). “what’s up GLEEKS? Having so much fun on set!! Can’t wait for you guys to see the episode!” she wrote.

So what do you think of her glasses and jacket? Creator Ryan Murphy has already said that Spears “wants to do a ‘Where’s Waldo?’-type thing with ‘Where’s Britney?’”—so is this a hint that she might be spotted somewhere in the library?
