New drama “Mistresses,” starring Alyssa Milano, Yunjin Kim, Rochelle Aytes and Jes Macallan, will premiere a week later than initially announced, on Monday, June 3 at 10:01 p.m. Based on the U.K. series, it will follow four girlfriends on their paths to self-discovery. And it will be sexy. Maybe.  

The show focuses on the stories of Savi (Alyssa Milano) a successful career woman working toward the next phase in her life, both professionally and personally; Savi’s free-spirited and capricious baby sister, Josslyn (Jes Macallan); their friends April (Rochelle Aytes), a recent widow and mother of a ten-year-old daughter, and Karen (Yunjin Kim), a therapist with her own thriving practice. These four friends find support and guidance with each other. The series is executive-produced by Rina Mimoun (“Privileged,” “Gilmore Girls”), K.J. Steinberg (“Gossip Girl”), Robert Sertner (“Revenge,” “No Ordinary Family”) and Douglas Rae (“Wuthering Heights,” “Camelot,” “Mistresses,” “Raw,” “Meadowlands”).
