Blake, 27, was snapped arriving at the God's Love We Deliver 2014 Golden Heart Awards in New York and was more than happy to give photographers a glimpse of her tum.
The Gossip Girl star was wearing a floor-length nude gown adorned with tiny embroidered flowers and it hugged her blooming stomach perfectly.
Blake had blow-dryed her long blonde hair into perfect loose waves for the bash, accessorising her finished look with dangly earrings and statement rings. Stunning!
Earlier this month, Blake confirmed on her website Preserve that she and actor husband Ryan Reynolds are expecting their first child together.
The US actress had written a post about expectant mums and shared many photos of them, before surprising fans with a picture of herself cradling a bump!
Blake and Ryan married in 2012 and spoke last year about their desire to have children together.
In an interview, Ryan said: "We'd love to have a big family. We both come from big families—my parents did four, Blake's did five. A lot of people say it's crazy, but we'll only know when we're there, you know?"
Meanwhile, Blake and Ryan aren't the only Hollywood stars to be having a baby. Earlier today, it was confirmed that The Holiday's Jude Law, 41, is expecting a baby with his ex-girlfriend, 23-year-old British singer Catherine Harding.
