Jennifer Esposito has joined ABC's summer sudser Mistresses in the role of Calista Raines, an uber-fabulous and larger-than-life Creative Director who will take Joss under her wing.

When Alyssa Milano decided to leave Mistresses as the production of the series moved to Canada, her character, Savi, either needed to be recast or leave, as well. The decision was made for Savi to move on with Milano leaving Joss (Jess Macallan) with a gaping hole in her life; one Calista will try to fill.

Unfortunately for Joss, there is a lot more to Calista than meets the eye. Calista is a very lonely woman and her fun, flamboyant nature is cloaking a darker side, and it's a world of mysterious secrets and betrayal she's more than eager to draw Joss into as she mentors her and behaves as her surrogate sister.

Esposito will join Macallan, Rochelle Aytes (April) and Yunjin Kim (Karen) to round out the four lead roles on Mistresses. If you need a refresher, you can watch Mistresses online via TV Fanatic to get the job done!
