The 27-year-old Gossip Girl actress gave birth in December, the New York Post's Page Six reports.

Blake announced her pregnancy on her lifestyle blog Preserve in October 2014. She shared this picture - taken by her brother Eric Lively - of her cradling her small bump.
"It's something that I've always wanted ever since I was a little girl..." Blake told US Weekly after the news broke. "I knew I wanted to have a lot of kids because I had come from a big family so it was always important to me. So it's just the excitement of that finally being here."

The sex of the baby is unknown and as for a name? Ryan has already been joking about the impressive title he'd like to give his first born.
"I don't want a name that's anything pretentious or, like, Hollywood-y," he told People. "So I'm going with Excalibur Anaconda Reynolds... that's if it's a girl."
Or maybe he'll go down the Disney-inspired route, like this celeb couple.
Congratulations to the proud new parents!
