The former Gossip Girl star was gorgeous as she attended the 2014 American Made Summit alongside its host Martha Stewart in New York City.
Blake's swapped acting for lifestyle advice in recent months, launching her own website, Preserve, which she was chatting about at the weekend's event.
She attended without hunky husband Ryan Reynolds, but he wasn't far from her mind as she spoke with the audience about being pregnant with the couple's first child.
Blake said (via People): "There is something in the water because all of my friends are pregnant suddenly. I'm always the one in charge of planning the showers and bachelorette parties and they are not letting me off the hook because I'm pregnant!"
Probably because you're so good at it, Blake!
The beautiful actress – who rose to fame playing Serena van der Woodsen in Gossip Girl - used her Preserve website to announce her pregnancy last month.
At the end of a post about mothers and family, Blake included a simple picture of herself sporting a baby bump, announcing her big news to the world in a rather classy and understated way.
Blake, 27, and Ryan, 37, married in 2012.
