Alec and Hilaria Baldwin are expecting another child together

Alec and Hilaria Baldwin are expecting another child together.

The mum-of-four took to Instagram on Wednesday, where she shared a video of the baby's heartbeat - conforming that their family is growing again. The 35-year-old wrote:

"It is still very early...but we have learned that there is a little person inside of me. "The sound of this strong heart makes me so happy—especially because of the loss we experienced in the spring. "We want to share this news as we are excited and don’t want to hide the pregnancy. "These first few months are tough with exhaustion and nausea...and I don’t want to have to pretend that I feel ok."

The Saturday Night Live star shared the video on his own Instagram account, which he captioned: "Well, I am delighted to say, 'Uno mas Baldwinito.' God is good." Friends and fans rushed to congratulate the couple, who wed in 2012, on their happy news. The little boy or girl will join big brothers - 16-month-old Romeo Alejandro David; three-year-old Leonardo Ángel Charles; four-year-old Rafael Thomas - and six-year-old sister, Carmen Gabriela. Baldwin is also dad to 23-year-old Ireland, from his previous marriage to Kim Basinger. The couple's news comes five months after Hilaria sadly revealed in a candid Instagram post that she was "likely" suffering a miscarriage, which she confirmed in a subsequent message to fans. Alongside a photo of her family, she said:

"There was no heartbeat today at my scan...so it’s over...but I have some pretty strong and amazing heartbeats right here. I am surrounded by such love and I feel so fortunate. "Thank you all for listening, for your support, and for sharing your own personal stories. We are stronger together...I hope this conversation continues to grow and that we stick together through both the beautiful and challenging moments in life."
