Jennifer Esposito has joined the cast of Mistressesand her character is definitely not making a good first impression.

(Milano opted not to return to the show after Season 2.) But if Calista's first encounter with Jos (Jess Macallan) is any indication, they'll either butt heads - or turn into the best of friends. Has Jos met her match? Watch the clip above!
