Good Wife season 7
Jeffrey Dean Morgan has been promoted to a series regular for The Good Wife season 7CBS

CBS's super-hit court room drama The Good Wife has hired Jeffrey Dean Morgan as a series regular for season 7.

The news has elated fans of Julianna Margulies's Alicia and they are hoping to see some crackling chemistry flying between the attorney and her hired investigator.

In the season 6 finale, Alicia and Finn's partnership ended as there was a lot of 'sexual tension' between them and Finn wanted to start a new life with his newly-reconciled wife.

TV Line suspects that Margulies's character will hire the calm and experienced hourly investigator to work at her new firm.

"We've loved and admired Jeffrey Dean Morgan for years, and we were thrilled to hear that Julianna did too, so it was a no-brainer to ask him to join our troupe," executive producers Robert and Michelle King said in a statement.

The previous season of the CBS drama was more about elections, campaigns and professional politics.

But Morgan's hire may bring the much needed romantic angle in the series after Josh Charles's controversial exit from the show in season 5. The romantic tension between Alicia and Will Gardner was one of the high points of the show.

CBS has also hired Emmy Award-winning actress Margo Martindale for the recurring role of Willa Eastman, a top campaign operative who will have a tiff with Eli in the upcoming series.

Martindale's character is described as "campaign operative responsible for past successes by underdog presidential candidates in Iowa who hides her intelligence and cunning under a fake, folksy charm," via Deadline.

This also implies that Peter Florrick's presidential storyline will be a part of the season 7 plot.

The Good Wife season 7 will premiere on CBS on 4 October.
