No returning show on television has gone through as many casting changes as Desperate Housewives.

The biggest, of course, was the addition of Drea de Matteo to the cast.

But Andrea Bowen and Jesse Metcalfe are also making returns to the series, while Orson Bean has landed a recurring role.

Now, the ABC hit has announced that Shawn Pyfrom won't be returning to the show on a full-time basis.

The actor has played Andrew Van De Kamp, the troubled son of Marcia Cross’s character, for years.

“Shawn’s not returning for a full season next fall,” a source confirmed. “But he’ll come back and make a few guest star appearances... His decision didn’t come easy, but he wants to pursue new television and film opportunities.”
