Alyssa Milano has been tapped as the last of the four leads in ABC’s drama series Mistresses. The soap, written by KJ Steinberg, is based on the British format. It centers on four women, April (Rochelle Aytes), Josslyn (Jes Macallan), Katie (Yunjin Kim) and Josslyn’s older sister Sarah (Milano), chronicling their sometimes scandalous romantic lives. Sarah is a classy and elegant married lawyer at a top Los Angeles law firm. Charmed and Melrose Place alumna Milano, recently seen in Garry Marshall’s romantic comedy New Year’s Eve, will next reprise her guest starring role on the Fox comedy Breaking In as the ex-wife of Oz (Christian Slater). She is with CAA and Alchemy Entertainment.

Amanda Walsh (Sons & Daughters) has joined Fox’s single-camera comedy pilot Rebounding, written by Joe Port and Joe Wiseman, exec produced by Steve Levitan and directed by Jason Winer. It is an uplifting comedy about Danny (Will Forte), a man recovering from the death of his fiancé with the help of the idiots on his pickup basketball team. Walsh will play the girlfriend of one of Danny’s friends, Dave (Hayes MacArthur). Walsh, repped by ICM and 3 Arts, replaces Aly Michalka, who was originally cast in the role but departed after the table read when the charcter was reconceived.
