After announcing her pregnancy on Monday morning, the former Gossip Girl actress took to her website, Preserve, where she shared the first photo of her growing baby bump with fans. In the photo, which was taken by her brother Eric, Lively cradles her sizeable bump in a black and white Sam and Lavi top and skirt.

"This will be the first child for Blake and Ryan Reynolds, who met on the 2010 set of The Green Lantern," E! News reported on Oct. 6. "The actors live in Bedford, New York."

Lively and Reynolds began dating in Oct. 2011, shortly after Lively's split from actor Leonardo DiCaprio and Reynolds' divorce from actress Scarlett Johansson. Eight months into their relationship, Lively and Reynolds bought their first home together, and on Sept. 9, 2012, they got married in a surprise wedding at the Boone Hall in Mount Pleasant, S.C.

Last month, during an interview with Marie Claire, Lively spoke about her desire to start a family with Reynolds, telling the mag, "If I could spit out a litter of kids, I would."

Reynolds has expressed interest in having more than one child, as well.

"We'd love to have a big family," he said in an interview with Details last summer. "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."
