Hilaria Baldwin Reveals New Baby Came Early

Hilaria and Alec Baldwin welcomed a son last week, earlier than expected.

— -- Hilaria Baldwin has not been shy about sharing her pregnancies.

Responding to comments on social media, Baldwin posted a belly-baring photo of her on Instagram, along with a detailed explanation.

"This is for those of you who are getting into some pretty serious arguments with each other about if I had a c section or not...this should clear it up: as you can see from this pic, I did not have a c section," the mother of two wrote.

She went on to address why she stayed in the hospital for a few days after the birth.

"Rafael came a little early (nothing extreme) so we just wanted to stay an extra night and make sure all is ok," she wrote. "Due dates are estimates and he came out a healthy weight. I'm actually lucky because given another few weeks, he would have been HUGE!"

Baldwin added, "We are overjoyed that we have a healthy little boy and also that I am feeling well."

This wasn't the first photo Baldwin posted showing off her post-baby bod.

Two days after his birth, she posed her underwear in the hospital bathroom to give women a more realistic picture of a woman's body after pregnancy.

"I have been planning on doing post belly photos but didn't know if I was gonna have the guts to actually follow through," she wrote. "I hope you understand my intention here: I believe it is important to accept and love our form after going through a bit of a battle bringing life into this world. Deep breath, here we go...all the way from my glamorous hospital bathroom ??"

Hilaria and Alec, who are also parents to two-year-old Carmen, announced their son's birth last week with a picture of a baby's tiny hand.

"We are happy to announce the birth of Rafael Thomas Baldwin," Hilaria posted on Instagram.

Later, she posted a quick look back at her second pregnancy.
