Claire Danes and her husband, Hugh Dancy, will be house hunting in preparation for welcoming their new baby.
The couple are apparently looking for a property in New York City that is suitable for bringing up children.
A friend of Hugh's told UsMagazine.com: ''They are definitely going to keep looking for new apartments in the city where they can raise a kid. They are New Yorkers and plan on being New York parents.''
Hugh, 37, recently finished his 'Venus in Fur' Broadway run, and 33-year-old Claire just wrapped production on season two of American TV show 'Homeland'.
She was nominated for Outstanding Lead Actress in a Drama Series at the Primetime Emmy Awards 2012.
The friend explained: ''Hugh and Claire decided a while back that they were going to have a child together. But they wanted to work their schedules around it.''
The couple - who starred in the 2007 film 'Evening' and married two years later - are enjoying every moment of her first pregnancy.
The source revealed: ''Hugh is so excited to be a dad. They are going to be amazing parents!''
Claire previously dated musician Ben Lee and 'Almost Famous' actor Billy Crudup.
