ABC’s The Mistresses has become a summer staple and now has been renewed for a fourth season. Jennifer Esposito, who joined the lead cast in Season 3, succeeding original co-star Alyssa Milano, will not return. I’ve learned that the Blue Bloods signed a one-year deal when she boarded Mistresses last year and, with her contract up, she is moving on. (Her character was last seen contemplating suicide in her prison cell.) Esposito is currently recurring on The Affair.

Mistresses has been a modest performer in Live+Same day ratings (average of 0.8 in 18-49 for Season 3) but has been a solid DVR gainer. Its Season 3 finale, which ended on a cliffhanger, adults 18-48 rating went up +57% in Live+3. Additionally, Mistresses is owned by ABC, and the drama was able to reduce costs heading into Season 3 by moving production to Canada. The soapy drama stars Yunjin Kim, Rochelle Aytes, Jes Macallan, Brett Tucker and Rob Mayes.

Based on the UK television series, Mistresses is executive-produced by Rina Mimoun, KJ Steinberg, Robert Sertner and Douglas Rae. 

Still no final word on the fate of ABC’s summer drama series The Whispers, whose actors were released back in June.
