FX’s Record-Breaking 18th Season of 'It’s Always Sunny' Is Finally on Its Way

The boys are officially on their way back to town — and Sweet Dee (Kaitlin Olson) is coming along too. After wowing audiences with an incredible 17th season of mischief, mayhem, and more half-baked plans than we can count, the crew behind It’s Always Sunny in Philadelphia are pushing forward with Season 18. Yesterday, in an Instagram post, series co-creator and star Rob Mac shared an image of a clapperboard with the words “It’s Always Sunny in Philadelphia 18” on it, signifying a major step forward for the beloved R-rated sitcom. In his caption, the Mythic Quest creator wrote “Back in the kitchen,” pointing to the stovetop that the clapperboard is resting on in the image.
