Maksim Chmerkovskiy and Peta Murgatroyd will soon have a tiny dancer on their hands.

The Dancing with The Stars pros revealed on Instagram Wednesday that they are expecting their first child together, with the mom-to-be gushing about her excitement for their baby's arrival. "We couldn't be happier. Baby Chmerkovskiy is coming," she captioned a photo, which showed Chmerkovskiy wrapped in a white towel and sitting in a chair, as he kisses Murgatroyd's baby bump.

Murgatroyd, 29, is all smiles in the photo, as she lifts her head up in delight and rocks a black sports bra and matching capri leggings. Chmerkovskiy also showed his excitement by posting their baby's sonogram on his Instagram page, writing alongside it, "Put your hand up if you're a #babyChmerkovskiy and you can't wait to drive your parents crazy! #cantwait #inlove #thatprofilethough," the dad-to-be, 36, captioned the photo.

The couple, who got engaged in December, plan to tie the knot in the summer of 2017, and told People Murgatroyd's pregnancy couldn't come at a better moment. "The timing is perfect, actually," Murgatroyd said. "I'll have the baby in January and then I'll still have about six months to prepare for the wedding." Chmerkovskiy added, "The baby will make a wonderful addition to the wedding party."

We can't wait to meet their little one!
