Hilaria Baldwin just revealed the gender of her second child.

She and Alec Baldwin are expecting a boy, she hinted on Instagram. A rep for the couple confirmed that the baby will be a boy.

"So we have an announcement to make...can you guess??" she wrote next to a photo of blue baby shoes. "Now, with this little baby growing inside of me, I will document for you how I am going to take care of myself while pregnant and beyond. There will be great tips if you are expecting or if you just want to learn really good exercises and nutrition tips....here we go again!!! #hilariahealthy2015"

Yesterday, the couple announced that they're expecting their second child together.

"The sun has set on 2014 and on my year of daily #hilariaypd ....2015 is going to be very exciting as we are thrilled to announce we are expecting another little addition to our family! (tadasana) #yogapostureoftheday," she wrote on Instagram, along with a sweet photo of her family.

"2015 equals Mommy, Daddy, Carmen, and a special guest star...." the actor added on Twitter.

The former "30 Rock" star, 56, and his wife of a year and a half welcomed their daughter, Carmen, in 2013. Baldwin also has an adult daughter, Ireland, from his marriage to Kim Basinger.

"I have the feeling that life is wonderful," he said of fatherhood in 2013. "I have the feeling that I’m so lucky, I’m so blessed."
