Wearing a clingy white pattered top, skinny jeans and comfy black ballet bumps, Claire looked blooming marvellous as she wandered through the US city.
And when the chilly autumn wind blew, Claire wrapped up warm in a cosy black cardigan.
Claire, 33, revealed in July that she is expecting her first baby with her husband Hugh Dancy,
But her pregnancy must have come as a shock to Homelands producers, as her bump hasn't been written into the script.
In an interview with America's Live! With Kelly, Claire admitted: "I've been pretty fortunate thus far - we're in the middle of filming our second season and luckily we've been able to conceal it.
"It's now getting to the point where I'm looking a little knocked up. They haven't written it in, but they'll be able to manipulate it in post and do some trickery and make Carrie not so pregnant."
