Maksim Chmerkovskiy & Peta Murgatroyd Give Update on Baby Shai

“Dancing with the Stars” pro dancer Maksim Chmerkovskiy is opening up about fatherhood after welcoming his son last week.

On Thursday, Maksim posted a pic of himself holding his son, who is barely seen in the snap. He wrote, "It's been one week plus one day of my fatherhood and I'm the happiest person that's ever lived. I'm also feeling very protective and now understand what every parent in history have been going through for as long as humans have been giving birth.”

As for why he hasn't shared a photo of Shai, the 36-year-old explained, "I don't let too many people come see my son and I don't want to put any of him on social media just yet. @petamurgatroyd and I just want to enjoy our little family, together with our loved ones, and take in all the precious moments which we'll never get back.”

Maks ended the post, saying, "P.S. Farts, poops and throw-ups are the best!”

In a separate post, Peta added, "We can't wait to share him with you, but for the first most crucial weeks of his life we're just keeping him for ourselves and soaking up these moments. Thank you for your patience and all of your love!"
