Season two of the Kaitlin Olson comedy has been extended by seven episodes.

The Mick is expanding at Fox.

The Kaitlin Olson comedy has earned an additional seven- episode order, bringing the show's season-two total to 20, The Hollywood Reporter has confirmed.

Premiering midseason on Fox, The Mick was a breakout out of the gate, becoming the network's top comedy launch since New Girl in 2011. The first season order was then extended by four episodes to a total of 17.

The single-camera comedy was continued to impress in season two, rising 28 percent for the season premiere as compared with the season-one finale.

It's Always Sunny grads John and Dave Chernin created The Mick and executive produce with Nicholas Frenkel, Oly Obst, Scott Marder and Olson. 20th Century TV produces the series.

TVLine was the first to report the news.

The increased episode order makes the return of Olson's other series, the long-running comedy It's Always Sunny in Philadelphia, uncertain. (Sunny airs on Fox's sister cable network FXX and is produced by sister studio FX Productions.) However, fellow Sunny star and co-creator Glenn Howerton is also starring in a network comedy, NBC's A.P. Bio, which is slated to launch sometime midseason.

Behind the scenes, the Sunny team of Howerton, Rob McElhenney and Charlie Day are also busy developing other projects, having already sold two comedies to Fox. Additionally, McElhenney is attached to the Minecraft movie and Day is juggling roles in several films, including Pacific Rim Uprising.

It's Always Sunny aired its last new episode, the season-12 finale, in March. The comedy is currently renewed through season 14.
