Showtime has renewed Nurse Jackie for a fourth season. The critically acclaimed dark comedy stars Edie Falco, who won an Emmy for her performance in the lead role this past season.
There is no word on the number of episodes ordered, but each of the show's first three seasons have been comprised of 12. The show currently has four episodes left in its third season, with the finale set for June 20. That same night Showtime will also air the series finale of their comedy United States of Tara, which was cancelled today.
