After telling him she's pregnant, he said he was "tearing up" at the news.

"We Are Having A Baby 🎉🙈🙏🏻Yes we know…we just had a baby… haha!", her post was captioned.

"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!" she added.

"Surpising [sic] @maksimc on this FaceTime with my two friends secretly filming from different angles made it all the more hilarious," she continued.

"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 🥴".

Murgatroyd, who welcomed her first child, Shai, with Chmerkovskiy in 2017, then went on to acknowledge "everything we've been through" to get to this stage.

"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," she wrote.

"We're just so happy that we can finally tell you guys the good news 🥹."

The couple married in 2017, six months after welcoming son Shai. They started dating on and off in 2012, and got engaged on stage during a performance in 2015.
