Showtime has ordered a fourth season of Nurse Jackie and has yanked United States of Tara from its premium lineup. Jackie, which stars the Emmy-winning Edie Falco, is currently averaging 2.8 million viewers.

Tara, which launched in 2009, has been good for Collette when it comes to racking up awards: She’s been nominated three times by the Emmys and won once. She also received a Golden Globe for playing a married mom with multiple personalities.
