Duhamel got his start on the ABC soap, playing Leo du Pres, a con artist who apparently died in 2003, though his body was never found. (Dun. Dun. Dunnnn.) The role landed him four Daytime Emmy nominations, including one win for Outstanding Supporting Actor in 2002.
The 38-year-old Las Vegas alum will return in at least one episode in August before the soap's swan song in September. Children will be replaced by The Chew, a one-hour live show centered on food.
