Who says you can't go home again.

Yes, that was Tina Fey wandering the halls of Upper Darby High School this week.

No, it was not her first time.

Yes, she knew her way around.

That's because Fey is an alum.

In fact, the 'Saturday Night Live' and movie star is enshrined in the school's Wall of Fame.

She was back in town to shoot a video for her 'Mean Girls: The Musical' production.

As we said on today's front page, she' Royal-ty.

You go, girl.
