Murgatroyd, 29, and her professional dancer fiancé Maksim Chmerkovskiy, 36, revealed exclusively in the latest issue of PEOPLE that they are expecting their first child together.

“I can’t wait to provide this baby with the tools to become a beautiful, kind person,” Chmerkovskiy told PEOPLE. “And they’ll have the best sneaker collection.”

Murgatroyd added: “I’m looking forward to nurturing something and just having the baby be the center of our world. I’m looking forward to putting all our energy into this beautiful soul.”

Although the parents-to-be initially wanted to wait to expand their family until after their summer 2017 wedding, they don’t mind the early surprise.

“The timing is perfect, actually,” Murgatroyd said. “I’ll have the baby in January and then I’ll still have about six months to prepare for the wedding.”

Chmerkovskiy agreed: “The baby will make a wonderful addition to the wedding party. A wonderful, tiny addition.”
