Alec Baldwin's wife is expecting a baby boy.

Hilaria Baldwin took to her Instagram account today (02.01.15) to hint at the sex of the couple's unborn child and to promise that she'll document every part of her pregnancy.

Alongside a photograph of four pairs of shoes - belonging to herself, Alec, their 16-month-old daughter Carmen and their upcoming new arrival - she wrote: "So we have an announcement to make to make... can you guess?? 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 of if you just want to learn really good exercises and nutrition tips... here we go again!!! (sic)."

The yoga fanatic announced her pregnancy yesterday (01.01.15) by posting a picture of Alec, 56, holding Carmen who is seen touching her mother's baby bump on a beach in front of a sunset.

The brunette beauty added the caption: "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 (sic)"

Meanwhile, the news will come as little surprise to fans of the couple - who married in June 2012 - as Alec recently admitted his 30-year-old wife is keen to have another baby in the near future.
