Has the Abbott Elementary Season 4 crossover been revealed? It’s Always Sunny in Philadelphia star Rob McElhenney shared a few fun photos from the set of ABC‘s Emmy-winning comedy alongside a few of its stars, raising the big question.

As fans will recall, star and creator Quinta Brunson teased that a crossover episode for Abbott Elementary was on the horizon, but the question of which crossover has loomed ever since. Thankfully, per confirmation from ABC, we can say that McElhenney’s behind-the-scenes photos do pertain to the much-teased crossover, although no additional details have been made available at this time.

While McElhenney’s posts did also feature himself alongside his It’s Always Sunny in Philadelphia stars, it’s unclear if the crossover will include their characters from the long-running FXX comedy or see the stars play themselves in the Abbott world. When the crossover was announced by Brunson, speculation picked up immediately with fans bringing up Always Sunny as a contender.

The two images shared by McElhenney, who plays bartender Mac on Always Sunny, first featured himself alongside Brunson and his long-time costar and collaborator Charlie Day, with all of them donning sunglasses.

The second photo added Abbott Elementary‘s Tyler James Williams, William Stanford Davis, and Always Sunny‘s Danny DeVito into the mix as they posed with Brunson, McElhenney, and Day.

Once again, with only a few details to go off of, regarding the crossover, we’ll have to stick to context clues for debunking whether this is an Always Sunny crossover or merely a crossover with its stars. The biggest hint that this is a crossover with Always Sunny‘s characters is DeVito’s dark hair and thick-rimmed glasses, signature to Frank Reynolds’ look.  The actor’s hair is typically grey when not filming for Always Sunny.

Stay tuned for any updates as we look ahead to this exciting crossover, and let us know what you think of the reveal in the comments section.
