Blake Lively and Ryan Reynolds are expecting their second child, according to reports.

The actress and the Deadpool star welcomed baby James 16 months ago, and now they're set to become parents again.

"Blake is absolutely thrilled and so is Ryan," a source told People.com.

Representatives for the couple have yet to confirm the baby news, but Lively appeared to be sporting a possible baby belly while zipped into a wetsuit for reshoots for her upcoming film The Shallows.

Lively tried to keep her swollen stomach hidden behind a robe, a towel and a surfboard, but the leaked photos clearly show her attempting to keep a secret.

The actress and her 39-year-old husband have not been shy about their hopes of having a big family, with The Sisterhood of the Traveling Pants star revealing: "I feel like my first child is going to be the oldest sibling to the next kid, and that may change with each and every year. I'm looking forward to how one baby influences the other, and to my family as a whole, to every single chapter."

Meanwhile, Reynolds will be preparing for a few more sleepless nights after grumbling about his daughter James's ability to stay up all night.

"Our baby, in particular, is, we think, allergic to sleep," he joked last March.

But he wouldn't have it any other way.

The youngest of four boys, the actor told People in February, "Having a daughter was a dream come true for me. I never admitted it out loud, to myself or my wife, but I really wanted a little girl."

It is not known whether the couple is expecting a baby boy or girl.
