Kristen Wiig joins Arrested Development as 'Lucille 3'

This may be the best news since Netflix announced it would be producing the fourth season of Arrested Development.

Comedic darlings Kristen Wiig and Seth Rogen are joining the show in guest-starring roles, Netflix confirmed to Us Weekly Tuesday.

No word yet on whom Rogen will be, but Wiig's casting is a doozy: the Bridesmaids and SNL star will be playing a young Lucille Bluth (Lucille 3... or is it Lucille 0.5?)!

Kristen Wiig as a young Jessica Walter? We definitely see it.

Wiig and Rogen join a slate of fantastic guest stars joining or returning to the series for the long-awaited fourth season. Liza Minnelli will be back in her role as Lucille Austero, a.k.a. Lucille 2, and new cast additions include late night funnyman Conan O'Brien, Mad Men star John Slattery, 24 alum Chris Diamantopoulos, Wedding Crashers babe Isla Fisher and Wiig's Bridesmaids co-star (and sometime Old Spice Guy) Terry Crews.

Netflix has confirmed the 14 new episodes of Arrested Development will debut all at once on its streaming service sometime in May.
