Pregnant Desperate Housewife Marcia Cross has been placed on bed rest by doctors - forcing the show's film crew to move into her home.The actress, who is expecting twins with husband Tom Mahoney in April, is confined to her house, but still needs to film two more episodes of the drama. Producers are so keen to keep Cross's character in the series, they are transforming her home into Bree Van de Kamp's - meaning the actress will have to walk no more than a flight of stairs to work. In October the actress announced she was expecting twins, telling US chat show host Ellen DeGeneres: "I was sort of blown away", but she did admit: "It's hard to carry around all that weight. I wake up feeling like me and then I step on the ground and I'm like, whose body is that walking to the bathroom?".
