Claire wore a bump-hugging black lace dress with semi-sheer panels, and patent black Christian Louboutin heels ($1017; shop.nordstrom.com).
Claire is expecting her second child with her husband of nine years, Hugh Dancy. The couple already welcomed their 5-year-old son Cyrus Michael Christopher Dancy in 2012.
"I'm knocked up!" Claire told the show's host, revealing her pregnancy has caused some problems during filming for the last season of Homeland.
"I was filming during the first trimester which is kind of my least favorite phase because you just feel horrible," she said. "You feel just rotten and you’re not allowed to say why."
"I was filming quite a lot but just inadvertently falling asleep all the time. And it was embarrassing," she added. "I face-planted onto this crocheted bag in-between takes. It was time for my close up… and I sit up and I have this crocheted indentation on the side of my face. It looked like I had third-degree burns."
Congratulations to the happy couple!
