Lost (my second favorite tv show just behind 24) has added two new hot cast members to their Hawaiian crew. Last week, it was confirmed that Rodrigo Santoro signed on the dotted line (my guess to get down with Evangeline Lilly's character). Today ABC announced that Elizabeth Mitchell has joined to possibly play Matthew Fox's love interest.

Elizabeth Mitchell has joined the cast of ABC's hit drama "Lost" as a possible new love interest for Matthew Fox's character, sources said. Earlier this week, Brazilian actor Rodrigo Santoro signed on to co-star on the show, which begins its third season in the fall.
Mitchell next will be seen opposite Tim Allen in the feature "The Santa Clause 3: The Escape Clause," which opens November 3. Her other credits include HBO's "Gia," in which she played Angelina Jolie's lover, and a recurring role on "ER."(source)
