A new little dancer just made his big debut!

Peta Murgatroyd and Maksim Chmerkovskiy welcomed a baby boy this morning in New York City, their rep confirms to People. His name? Shai Aleksander! We wonder if they will hyphenate his last name? If so, that's a mouthful!

“This is, without a doubt, the best thing that has ever happened to us!" the couple said in a statement.

The pair got engaged on the dance floor in December 2015 and announced they were expecting in June.

Congrats to the new parents!
