Alec Baldwin is daddy-to-be once more!

Hilaria Baldwin, the "30 Rock" star's yoga instructor wife, shared the good news that she and her actor hubby are expecting their second child as a couple together on Thursday with an Instagram photo.

The sweet snapshot showed the soon-to-be parents and their daughter, Carmen, spending some time together on a beach at sunset.

"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!" Hilaria captioned the pic.

The sun-dappled snap showed Alec kneeling on the sand and clutching 1-year-old Carmen as she stroked her mama's exposed belly.

The 56-year-old actor also shared the big news on his Twitter page, posting a link to his wife's Instagram photo.

"2015 equals Mommy, Daddy, Carmen and a special guest star...." he tweeted.

Hilaria's photo and pregnancy announcement immediately sparked massive response from social media users. The 30-year-old beauty is known to be an avid Instagram user, posting photos of herself in body-contorting poses daily.

Carmen's younger brother or sister will be the third child for the "Inception" star, who tied the knot with Hilaria in a star-studded ceremony at St. Patrick's Old Cathedral in Nolita in 2012.

He shares one daughter with ex-wife Kim Basinger, 19-year-old model Ireland.

Meanwhile, another star was the subject of pregnancy rumors late last month, after reports surfaced suggesting that Rihanna was expecting her first child.

The unnamed sources went so far as to provide a fake sonogram of the singer's unborn child.

Despite the massive social response the fake report sparked, the "Diamonds" hitmaker was apparently unfazed and simply laughed off the pregnancy rumors, according to
Hollywood Life.

"She thinks it's absolutely hilarious," a source told the celebrity news site. "But, she really doesn't pay much attention."

The source mentioned that although Rihanna has been posting a plethora of pictures with her young niece, the singer doesn't have "baby fever," as some media outlets claim.

"The only baby she has is Majesty and she treats her niece as if she were on her own daughters. She spoils her rotten and loves her to death."
