She and husband Hugh Dancy, 37, announced that they are expecting their first child, according to People.
The Homeland star, 33, and the Martha Marcy May Marlene actor wed in 2009 in a private ceremony in France, and lately, Danes has had babies on the brain.
“There’s definitely a chance, no plans yet,” the My So Called Life alum said this past fall when asked about having kids. “But yeah, that’d be fun.”
Danes’ pregnancy is not expected to affect production of her hit Showtime series Homeland, which returns on Sept. 30. The actress won a Golden Globe for her role on the program this past January.
