The longtime dance pros and show rivals welcomed their first child, a boy, on Wednesday in New York City. They named their son Shai Aleksander Chmerkovskiy. His first name means "gift" in Hebrew. His middle name is a tribute to Maks' father, Aleksandr.
Meeting on Broadway: Maks, a New Yorker born in what was once Soviet-ruled Ukraine, and Peta, an Australian born in New Zealand, met when they both starred with other DWTS pros in the Broadway show Burn the Floor. The show debuted in 2009, three years after Maks made his debut on season two of Dancing With the Stars.
