ABC has renewed “Mistresses,” giving a fourth season to the mystery-tinged summer sudser.

Hailing from ABC Studios, “Mistresses” is executive-produced by Rina Mimoun, KJ Steinberg, Robert Sertner and Douglas Rae. The story of four female friends and their illicit encounters is based on the U.K. series of the same name created by Lowri Glain and S.J. Clarkson.

It stars Yunjin Kim as Karen Kim, Rochelle Aytes as April Malloy, Jes Macallan as Josslyn (“Joss”) Carver and Brett Tucker as Harry Davis, and Rob Mayes in the role of Marc Nickleby. Alyssa Milano left the series after the second season when production moved from Los Angeles to Vancouver.

The 13-episode third season of “Mistresses” finished up on Sept. 3 with 2.7 million same-night viewers. Although that’s nearly a 1 million drop from its previous season’s finale, the series was still the strongest performer throughout summer among ABC’s Thursday dramas, which also included “Astronaut Wives Club” and “Rookie Blue.”
