A “nun” takes a selfie with her beer at Citizens Bank Park. (Twitter)

There’s nothing wrong with being a little rebellious. And this “nun” had her fun, or at least pretended to for a quick selfie with her Miller Lite at a Phillies game.

Apparently, it’s completely okay for “religious folk to tilt a glass back now and again.” For a while, some nuns even brewed beer.

Or drink, in this case. (Thank you Sister Mary Clarence.)

But these “nuns” aren’t really nuns. They’re members of the cast of a local production of “Sister Act.” And they weren’t just partaking in alcohol-related activities. They got their cheer on too.

They even got to dance with the Phanatic on top of the dugout.

Some cast members sang the national anthem.
