Showtime confirmed this week that Maggie Grace and Jorge Garcia will both guest star on "Californication" this season, forming a "Lost" reunion.

It will, however, be a short-lived reunion, because while Grace will appear on at least eight episodes, Garcia will only drop by for one week.

Grace will play Faith, a former rock-n-roll groupie who develops some sort of relationship with David Duchovny's Hank Moody. The character has been positioned as the centerpiece for a possible spinoff.

Garcia will drop by playing an old contact from Faith's past, whatever that means.

Also guesting on the sixth episode of "Californication," which will premiere in early 2013, is Tim Minchin, who is described as a "musical comedy phenom."
