This is no April Fool's joke: Scott Bakula will makes his Desperate Housewives debut on April 1.

The veteran actor (most recently seen on Chuck and Men of a Certain Age) comes on board the stretch run of this ABC series as a high-powered attorney hired by Bree when she becomes a suspect in the murder of Gaby's stepfather.

Before we take that journey down Wisteria Lane, however, Desperate Housewives will air a new episode on March 25.
