Samsung Celebrates Alec Monopoly's LEVEL Headphones CollaborationMake room for another Chmerkovskiy boy! "Dancing With the Stars" pro dancer Peta Murgatroyd has given birth to her first child, a son with fellow pro Maksim Chmerkovskiy. They just welcomed little Shai earlier today (Wednesday, Jan. 4).

Maks and Peta revealed their son's name and birth details via Twitter:

Maks's brother, fellow pro dancer Val Chmerkovskiy, posted an Instagram video yesterday saying he had to cancel that night's tour show because he was expecting to be an uncle very soon, as soon perhaps as he stopped filming the video, and he wanted to be there with the family. Maks also shared a photo of Peta in the hospital, preparing for delivery ... and freshening up for any cameras:

But first...a little make up ????

Maks, 36, and Peta, 30, got engaged in December 2015 after their on-and-off relationship started in 2012. The Ukraine-born hunk was previously engaged to DWTS pro Karina Smirnoff. Maks won DWTS Season 18 with Meryl Davis and competed in the most recent Season 23 with Amber Rose (who may or may not be now dating Val). Peta, who was raised in Australia, won Season 14 with Donald Driver, and Season 22 with Nyle DiMarco, but skipped this past fall 2016 season (which Val won, with Laurie Hernandez) due to her pregnancy. Maks has said he has no interest in being on Season 24 this coming spring 2017 because he wants to be a stay-at-home dad while Peta pursues her dreams.

Congrats to the happy family!
