“I think that it’s a great bonding activity for the whole family to do,” Murgatroyd said. “At first we didn’t have anybody to look after Shai so we just took him along and it just became an every week thing. We take him to the gym now and we bond together over there.”

“I think if you introduce an activity like a gym, a workout at an early age, there’s nothing wrong with that,” Chmerkovskiy added.

With the wedding so close, a source told Entertainment Tonight that the couple’s five-month-old son Shai to be their ring bearer.

“Maks and Peta’s wedding will be something to remember! It will be a huge wedding that will span the course of a three day weekend,” the source said.
