It's Always Sunny in Philadelphia wrapped a strong twelfth season in early March, but fans may have to wait longer than usual to get a glimpse at season 13.

How long? Try 2019.

Kaitlin Olson, who plays Sweet Dee on It's Always Sunny, recently spoke with TV Guide about the show, telling the publication that they "ended up pushing our next season a year." That's not exactly great news for It's Always Sunny die-hards.

"We were all busy with separate projects this year," Olson, star and co-executive producer of Fox's The Mick, said. "So at the end of this coming shooting season of The Mick, I'll step right into Sunny after that."

As TV Guide notes, that purported delay in filming could push the season 13 premiere of It's Always Sunny into early 2019. The show has debuted its last three seasons in January, though earlier seasons kicked off mostly in September. Neither production nor air dates have yet been set, FXX told TV Guide.

The show, however, will go on. As Deadline reported last year, It's Always Sunny is on the hook for seasons 13 and 14 of the show at FXX. Star Glenn Howerton, who plays Dennis, may not return, given the finale of season 12 this year.

Howerton told The Wrap in March that he "might be" done with the show, and that it "may be taking an extended hiatus between season 12 and season 13." The actor is currently involved with a sitcom pilot for NBC formerly titled AP Bio, a show from Seth Meyers and SNL's Mike O'Brien featuring Howerton and comedian Patton Oswalt.

Olson's The Mick is set to air its first-season finale this week, but don't expect her obligations there to let up soon. Fox announced a second season earlier this year.

It's Always Sunny cocreator Rob McElhenney, known to fans of the show as Mac, is working on Minecraft, a movie about the popular video game, a project he's been attached to since 2015. indicates the McElhenny-helmed film starring Steve Carell is scheduled for a 2019 release.

Charlie Day, meanwhile, will next appear in Pacific Rim: Uprising, set for release next year. Danny DeVito, who plays Charlie's best friend, Frank, on It's Always Sunny, is currently performing in a Broadway run of Arthur Miller's The Price that closes Sunday.

Season 12 of It's Always Sunny was a record-breaker for FXX. The season's premiere was the network's most-watched original telecast ever. The show is also on track to tie The Adventures of Ozzie and Harriet as TV's longest-running live-action comedy once season 14 airs, whenever that may be.
