It has been announced that Stockard Channing is set to join The Good Wife.

Channing is as famous for her work on Broadway as on the big and small screen but is probably best known for playing Abbey Bartlet on The West Wing and for her iconic role as Rizzo in Grease.

Entertainment Weekly reports that Channing is set to take on the role of the mother of Alicia played by Julianna Margulies. She is set to appear in at least one episode in the fourth season and the character is described as "mercurial and influenced by her 1960s counterculture youth."

The new season of The Good Wife starts in the US on CBS this weekend.
