Did you know that four members of the gang are married to each other in real life? It’s true! Can you guess who?

Charlie may be chasing stalking the Waitress on It’s Always Sunny In Philadelphia, but he’s actually married to her (Mary Elizabeth Ellis) in real life. They started dating before It’s Always Sunny In Philadelphia started and got married in 2006. They have a son together named Frank Russell.

Mac and Dee would seem like they would be a very odd couple based on the show, but they are married in real life too. They actually met when Mac (Rob McElhenney) interview her (Kaitlin Olson) for the role of Dee. They got married in 2008 and have two sons. True Philadelphians, they own a bar in Philly called Mac’s Tavern and Kaitlin even went into labor at a Philadelphia Phillies game.

Last, but not least, Dennis (Glenn Howerton) is marred to Jill Latiano, an actress that starred on It’s Always Sunny In Philadelphia in the episode The D.E.N.N.I.S. System. The D.E.N.N.I.S. system probably worked, but they were actually married two months before that episode.
