WOOT WOOT! It's now been confirmed that production and writing of Season 14 of Always Sunny is in progress! In fact, Dennis, Mac and Charlie are back in the writing room together as per Rob McElhenny's recent instagram post.
The previous season of 'It's Always Sunny In Philadelphia' concluded in November 2018 with a landmark episode which addressed Mac’s (played by Rob McElhenney) sexuality.
Charlie Day and Glen Howerton both then followed up McElhenney's post by each uploading another picture of the trio together, with the latter remarking: “The boys are back in town. #sunny14”. YASS!
