Graham, whose last foray into TV was the ill-fated ABC sitcom "Emily's Reasons Why Not," is joining Season 7 of Showtime comedy "Californication" for a season-long arc, Deadline reports. She will play a woman from Hank's ( David Duchovny) past whose arrival disturbs his life.

Also joining the show for a three-episode arc in Season 7 is "24" alum Mary Lynn Rajskub. She'll be portraying a neurotic writer.

This bit of casting news comes just a few days after word that "Sopranos" alum Michael Imperioli has joined the show in a major recurring role, as well. He'll be playing Rick Rath, a successful old-school television producer who will play a key role in Hank's latest venture.

The 12-episode season will go into production at the end of April, eyeing a premiere in 2014.
