We already reported that Glee is set to do a Britney Spears-themed episode this fall. And although we’re not sure if Britney is actually making a cameo herself, it looks like Lea Michele will step into Spears’ shoes—literally! We spotted Michele on the set of Glee in L.A. looking like Brit’s doppleganger in a costume from the “Hit Me Baby One More Time” video. And with rumors circulating that Matthew Morrison is going to shave his head a la Britney Spears 2007, we already can’t wait for the episode to air.

UPDATE: It’s official! Britney Spears will appear on Glee, according to People.com. “Britney, I think 100%, is going to be the episode,” creator Ryan Murphy told Ryan Seacrest on his radio show yesterday.
