Maksim Chmerkovskiy has a lot of respect for his hardworking fiancée, Peta Murgatroyd!
ET caught up with the 37-year-old dancer during a Dancing With the Stars
rehearsal with his season 24 partner, Heather Morris
, on Tuesday in North Hollywood, California, where he couldn't stop gushing over Murgatroyd's work ethic.
As fans of the couple know, the two welcomed their first child, son Shai, in January. Since then, Murgatroyd hasn't been shy about documenting her journey to shedding the baby weight via social media, and will be taking the stage with Bachelor
star Nick Viall when the new season premieres on ABC on Monday, March 20. Yes, just two months after giving birth, the blond beauty is back to work
"It's insane, it's insane," Chmerkovskiy told ET's Cameron Mathison. "I'm not a good enough spokesperson to explain this, this process, but it's -- my hats off [to her] is an understatement."
"It's fun! We get to dance for a living, it's amazing," he continued. "But Peta has a much harder job than I do. Because she's a mom. What women go through with pregnancy -- [is crazy]."
Luckily, they have a wonderful nanny who takes care of Shai while the two are busy performing and in rehearsals.
"She knows what she's doing, and yeah, no, we trust her," the father of one joked. "But it's amazing. I met her kids. It's just something that I can't wait for ours to be [13 months, like Heather's] youngest age. He just walks around doing his things, pulling on some plants, keeps hitting his head everywhere, just smiles through it.”
"I'm excited for that period of time," he added. "I don't know when that happens, but it's different. He'll say something at six months or whatever, hopefully, and then that's it."
As for whether Shai will follow in his parents' footsteps and be a dancer someday?
"Hopefully not," Chmerkovskiy joked, adding, "What if he's like 10 and he's like, "I want to be a doctor and not on the cover of a magazine.'"
"True reality is that we share maybe one, two percent, you know?" he continued on his and Murgatroyd's decision to keep what they share about their newborn to a minimum. "There's just so much stuff that we're keeping to ourselves."
