Jane Bingham will find herself in hot water in the new season of Drop Dead Diva with a slew of new clients from her past.

Price (Rules of Engagement) will appear in the season premiere as Emily Horn, an intelligent but manipulative socialite who was a former law school classmate of Jane's. She'll turn to Jane for help when she's brought up on murder charges. She only knew the old Jane, which makes it awkward when this Jane begins to suspect she really is a cold-blooded killer.

Duke, who won the Academy Award for her portrayal of Helen Keller in The Miracle Worker, will appear in the third episode as Rita O'Reily, a career floor-greeter who is fired after heroically stopping a shoplifter. When Jane takes on her case -- over which Judge Singer will preside -- she begins to wonder whether Rita may also be inhabited by someone else.

In that same episode, Rutherford (The New Adventures of Old Christine) will play Olivia French, the quick-witted sister of Jane's boyfriend Judge Owen French (Lex Medlin). Owen will enlist Kim's (Kate Levering) help in navigating Olivia's divorce. Why not ask Jane? Because the old Jane broke the heart of Olivia's friend.

Drop Dead Diva returns for its fourth season this summer.
