In an exclusive interview with In Touch, Dancing With the Stars pro Maksim Chmerkovskiy admits he is more confident on the dance floor than he is changing the diapers of his son Shai — whom he welcomed with DWTS co-star and fiancée Peta Murgatroyd in January.

“It’s not like anything I’ve felt before, but it’s also terrifying. I’m so concerned about doing the right thing!” Maks says of fatherhood “Everything has a residual effect. It’s not like I’m walking on eggshells, but I have to be responsible for my actions and my words.”

“I will inevitably be happy as long as Shai and Peta are happy, but if they are not, I will never be happy.”
