Exclusive: Brothers & Sisters Adopts Two and a Half Gal

Marin Hinkle by Cliff Lipson/CBS
Marin Hinkle is cornering the market on bitter ex-wife roles.
The
Two and a Half Men actress (she plays John Cryer's uptight ex) has been cast as Courtney McCallister, the bitter former spouse of Rob Lowe's Sen. McCallister, on
Brothers & Sisters. She'll appear in one episode this fall, but it's likely she'll be back for more. In the episode, Courtney goes on a
Larry King Live-type talk show to discuss her estranged hubby's bid for the White House - further inflaming tensions between the two.
Since Hinkle is a series regular on
Men, it's safe to say that she had to get CBS and Warner Bros.' OK before committing to
B&S.
In other casting news, Tom Everett Scott has sealed a deal with ABC's
Cashmere Mafia to play the fiancé of Lucy Liu's character - which is a little strange since in the pilot
I saw she was definitely single. I'm sure there's a very good explanation for that. Or not.
