Peta Murgatroyd's baby bump is getting so big! Maks Chmerkovskiy posted an adorable video of his pregnant fiancée on Instagram a month before her due date.

"After long day of meetings and other events, this is what happens," he began in the video. The camera then panned to an exhausted Peta sitting on the floor against a wall.

Peta moaned as Maks walked towards her. They both started laughing as Peta said, "I'm too big to get up." But Maks jokingly told the camera, "No she's not."

Maks then captioned the video, "When queens get tired they sit down....wherever they can!@petamurgatroyd put up a good fight, but #babyChmerkovskiy always wins #FourMoreWeeks #InLoveWithThisChick."

Indeed, Peta's baby boy is due around January 2. And they are making the final preparations for his arrival. Over the weekend, they attended a Lamaze class, though they got kicked out because Peta wasn't paying attention.

The couple has also been busy setting up their son's nursery. Peta previously said that she wanted the room to include neutral colors with a little bit of blue.

Peta and Maks have picked out a name, as well. They haven't revealed what it is, though Peta recently told HollywoodLife that it will be "short." That's because the boy's middle name, Alexander, and last name, Chmerkovskiy, will be long. Peta also said that they initially wanted to name their son Kai but had to change it when their friend gave her child the same name.

The DWTS pros are clearly excited to become first-time parents. And it sounds like their son is already following in their dancing footsteps!

"I’m sure he will have a little bit of rhythm," Peta added. "I kid you not, on the way to this interview he was kicking my rib cage like no other — he doesn’t kick and retract, he keeps [the kick] and extends his point… In our last ultrasound they told us that he has very long legs."
