"It’s a …….BOY! 🩵🩵🩵 I’ve been quietly preparing myself to be a real-life wolf pack Mumma with our THIRD baby boy on the way 🙏🏻🤣💙," the couple wrote in their caption.

"I CANNOT BELIEVE WE WILL HAVE 3 BOYS!! 🤣🤣🤣🤣🤣🤣 Maks and I are beyond happy to have another buddy for Shai and Rio…we want them to be the best of friends and thinking about family dinners already makes us laugh! Not to mention when Rio turns 1 , I will give birth to this bundle of joy a couple of weeks later 💃🏼💃🏼💃🏼."

The expectant mom concluded her caption by asking her fans to drop name suggestions in the comments section.

In February, Murgatroyd announced her pregnancy on Instagram by sharing a video of her positive pregnancy test over FaceTime, surprising Chmerkovskiy.

"We Are Having A Baby 🎉🙈🙏🏻," she wrote in the post’s caption. "Yes we know…we just had a baby… haha! This was very unexpected at (4 months postpartum with Rio) but we are sooooo happy and so ready to be a family of 5 soon!"

During the video chat, Chmerkovskiy was “tearing up” shortly after his wife told him the happy news, although they quickly started worrying about what they're going to do as they discussed needing a bigger house. Murgatroyd wrote in the caption that it was “hilarious” telling her husband over FaceTime.

“It took one hour for me to get the courage to call him 😂 and when he wasn’t catching on we all couldn’t stop laughing in the kitchen. I had the 'I’m so sick story' the pickle and 2 bottles HAHA! Oh Maks 🥴.”

She continued, “After everything we’ve been through with miscarriages and IVF we’re beyond blessed and know we are uber lucky for this miracle to happen to us. We’re just so happy that we can finally tell you guys the good news 🥹.”

Although it was a bit of a shock, Chmerkovskiy has shared that he's excited to become a family of five.

"It's definitely a dream come true, all those beat-up phrases," Chmerkovskiy told PEOPLE after sharing the couple's news. "I'm extremely excited to be in this position, in this place in my life. I am also very aware of the perspective, of where I come from, of where I am now."

"I dreamt about this before. The family with somebody that I really want to have a family with. This unconditional love and house and it's all of that. I'm also very much aware that it's not that for everybody."
