The Good Wife has tapped an Oscar nominee and former (fake) First Lady to come on board as Alicia Florrick's mother.

As reported by Entertainment Weekly, Stockard Channing will appear in at least one episode of the CBS drama as an outspoken woman shaped by the counter culture 1960s.

It's unknown at this time just what brings her back into her daughter's life.

For TV fans, Channing is best known for portraying Abbey Bartlet on The West Wing, while movie fans will also know her a Rizzo in Grease.

The Good Wife Season 4, meanwhile, kicks off Sunday night.
