The "Gossip Girl" star shared a photo of her growing baby bump on her website, Preserve, to announce that she's expecting her first child with husband Ryan Reynolds.
The pretty pic, taken by her brother Eric Lively, shows the actress wearing a stunning black and white print dress as she cradles her bump proudly.
The blonde beauty has been open about wanting to start a family since she married the actor in September 2012. "I gotta get started," she told Marie Claire in its September 2014 issue. "If I could spit out a litter of kids, I would."
"He's going to be a great father and leader and patriarch—he's so meant to be all of those things," she added in Vogue. "The fact that he lived so much before we got together, he's the exact realized person that he should be. And so I get to share my life with the person he's become, and we get to grow from there."
The cute couple met while shooting their 2011 movie, "The Green Lantern," and secretly said "I Do" in a private ceremony in fall 2012.
