Watros, 41, will play James Wilson's (Robert Sean Leonard) first ex-wife and the doctor's rekindled love interest, according to a show insider. She is set to appear in multiple episodes.
The Emmy winner (for Guiding Light) is best known as Libby on Lost, a role she is set to reprise this season. Since being killed off the show in 2006, she's guest-starred on Men of a Certain Age and starred in a string of failed pilots, including last year's Gossip Girl spin-off Valley Girls
