Congratulations to Peta Murgatroyd and Maksim Chmerkovskiy as the Dancing With the Stars pros have welcomed a baby boy!

The birth of their bundle of joy was confirmed by the couple's rep in a statement to Us Weekly.

"We can confirm that Peta and Maks have had their baby boy, Shai Aleksander Chmerkovskiy, born on Wednesday, January 4th at 5:34 a.m. Per the couple, 'This is, without a doubt, the best thing that has ever happened to us!'" the statement read.

Maks also announced the happy news via social media.

Hours before the announcement of their son's birth, Chmerkovskiy posted a video of what appeared to be the couple zipping down a roadway likely en route to the hospital.

And Chmerkovskiy's brother, Val, posted a video to his Instagram account revealing that he was "expecting to be an uncle very soon."

Reports surfaced last May that Murgatroyd was pregnant with the couple's first child. They got engaged in December 2015.
