Homeland producers have enlisted a body double to fill in for pregnant star Claire Danes, according to her co-star Damian Lewis.

The actress, who is expecting her first child with husband Hugh Dancy, has been determined to shoot as many scenes as possible in her role as Cia officer Carrie Mathison, despite her advancing pregnancy.

However, Lewis reveals he has recently been working with a slim stand-in because Danes is now "showing considerably".

He tells Britain's Hello! magazine, "She has a belly-double now. A very nice lady who turns up occasionally to reshoot some of Claire's scenes. She's called Meredith and I've got to know her quite well...

"(Danes is) doing unbelievable well with the pregnancy, although she's showing considerably now. She's extremely apologetic about the timing - which, obviously, isn't ideal - but as we all know, you don't time these things, do you?

"She didn't want the story to be compromised, so you won't suddenly see her character Carrie sitting behind a desk and typing with her belly hidden or anything like that."

Both Lewis and Danes scooped Emmy Awards for the drama last month (Sep12).
