The 38-year-old actress is set to star as the late wife to her real life husband, Jeffrey Dean Morgan‘s character, Negan.
ComicBook.com revealed that AMC announced that Hilarie would play Lucille in a special episode.
In the comics, Negan was married to a woman named Lucille prior to the end of the world, and she was battling cancer.
Negan was depicted as having an extramarital affair, but after Lucille’s diagnosis, he began to spend as much time with his wife as possible, and he called off his affair.
Lucille did pass away, however, it was just as the zombie virus beginning to spread and she was reanimated as a walker.
The Walking Dead is expected to return for six more episodes before wrapping up the series on the network.
