Other guest stars set to join the dramedy about a drug-addicted nurse as she heads toward rehab -- and divorce -- include new hospital administrator Bobby Cannavale, Rosie Perez, Sopranos alum Aida Turturro and Oscar winner Joel Grey.

Season 3 ended with Anna Deavere Smith’s Gloria Akalitus -- the now former top dog at All Saint’s -- essentially holding Jackie’s (Falco) fate in her hands before disposing of a urine sample that more than likely could have spelled doom for the pill-popping nurse.

Season 4 of Nurse Jackie kicks off April 8 on Showtime.

Will it be the time of Armstrong's life? What do you think of the potential pairing?
