Despite another season of low ratings, zABC has renewed their Mistresses TV show for a third season. The 13 new episodes are expected to air next summer.

Based on a British series of the same name, Mistresses revolves around the lives and loves of four sexy female friends. Performers include Alyssa Milano, Rochelle Aytes, Yunjin Kim, Jes Macallan, Jason George, and Brett Tucker.

The second season averaged a 1.0 rating in the 18-49 demographic with 3.71 million viewers. That was down year-to-year by about 16% in the demo but was even in viewership.

UPDATE: Though Mistresses will return for season three, Alyssa Milano will not. The actress says, “After two wonderful seasons in Los Angeles, the studio has decided to shoot Season 3 of Mistresses in Vancouver, Canada for financial reasons. It’s with a heavy heart that I have decided that I can’t relocate. I have two babies under 4. Being a mother and wife comes first, and I just can not uproot my children and separate the family by moving away. I will miss this job desperately and wish everyone the absolute best.” It’s unclear how her departure will be handled.

What do you think? Are you glad to hear that Mistresses has been renewed? Will you miss Milano? How long should this series run?
