Angie Harmon is slated to guest-star as Gigi, the insane ex-wife of Sam's current beau, Winston Funk (Billy Zane), a show rep tells TVGuide.com. Harmon, last seen on the small screen in Women's Murder Club, is scheduled to drop by on the ABC series' 19th episode, titled "The Other Woman."
Bumped by inflated Bachelor episodes, Samantha Who? is tentatively scheduled to return Jan. 26.
What do you think of Harmon's casting? Can she hold her own against Christina Applegate?
