Blake Lively is pregnant with her first child, she announced on her website, Preserve today.

It was a subtle message from her lifestyle blog -- just a note to say that "Family is the single word our founder, Blake built this home on."  Blah, blah, blah, and then "Congratulations to all expecting mothers out there."  And then a few photos of pregnant friends celebrating in an all-to-perfect setting with extravagantly decorated tables and a hot service staff AND ... a photo of Blake (shot by her bother Eric) holding her baby bump!

Blake and hubby Ryan Reynolds have been talking about starting a family for quite a while.  Blake told Marie Claire in this September's issue, "If I could spit out a litter of kids, I would."  Back in 2012 she told the same mag, "I gotta get started."  Ryan told Details last year, "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."

The couple met on the set of The Green Lantern back in 2011 and then wed secretly in South Carolina in the fall of 2012.  Blake and Ryan live in upstate New York and are famously private and camera-shy.  We just hope they keep posting photos of Blake's baby bump -- she looks beautiful!
