Start the countdown! Before we know it, there will be a brand new and tiny addition to the Dancing with the Stars family.
"Our little man will be here before we know it," she wrote.
This is her first child with fiancé and fellow DWTS pro Maksim Chmerkovskiy. The two got engaged during the "Sway: A Dance Trilogy" show in Miami back in December, and announced their pregnancy toward the end of the last season of DWTS.
Murgatroyd won the last season with partner Nyle DiMarco – who realized that his pro partner was pregnant way before she told others. She isn't competing this season, but her fiancé is. Chmerkovskiy is dancing with actress Amber Rose.
Perhaps the little one will get a stunning mini-mirror ball trophy for his birthday if dad takes home the win.
