Blake's having a baby! Blake Lively is pregnant and expecting her first child with husband Ryan Reynolds, the actress and model has announced on her website, Preserve.

Somewhat cryptically, Lively launched a Preserve Celebration of Family on her website, celebrating in particular “that special moment at the creation of family.” She published an array of pictures of happily pregnant ladies, and after congratulating “all the expecting mothers out there,” the Gossip Girl alum added in one extra picture — of her blooming pregnant belly!

The snap, taken by her brother Eric Lively, shows Blake posing in the twilight, wearing a stunning printed top and skirt by Sam & Lavi, cradling her bump proudly.

Lively has been quite vocal about wanting to start a family since marrying Reynolds in September 2012. "I gotta get started," the sunny actress told Marie Claire in its September 2014 issue. "If I could spit out a litter of kids, I would." Read Blake's sweet baby announcement.

Her sentiments mimic those of her hunky husband. "We'd love to have a big family," Reynolds told Details in its August 2013 issue. "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? We’ll walk through that fire pretty happily, I think."

Lively, in fact, hinted in Vogue's August 2014 issue that they could be walking through that fire pretty soon. "He's going to be a great father and leader and patriarch — he's so meant to be all of those things," she gushed of her hubby. "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." (Reynolds was previously married to Scarlett Johansson from 2008 to 2011. Coincidentally, Johansson welcomed her first child, daughter Rose, with fiance Romain Dauriac earlier this month.)

Lively and Reynolds first met while shooting their 2011 movie, The Green Lantern, and secretly wed in an intimate South Carolina ceremony in fall 2012. Since tying the knot, the A-listers — when they're not busy promoting new movies or working on entrepreneurial endeavors — have maintained a low profile in their Bedford, N.Y. home.
