"I want to experience that relationship," Maksim, 40, told Us on Monday of having a daughter.
"When Peta said [her last pregnancy] was a boy, I had this elated reaction like, 'Thank God.' But immediately after that, I was like, 'Okay, now I'm ready for a girl.' I just think it's a special thing."
Maksim also admitted his mother is "looking forward" to having another grandchild.
"She's dying [for a girl], but I am too," Maksim shared.
Peta, 33, is apparently hoping to get pregnant as soon as possible. She revealed in October 2019 she and Maksim hoped to conceive a second baby before the next season of Dancing with the Stars commences.
"I would love to have more kids," Peta told the magazine at the time.
"We're talking about it now and trying to -- it sounds crazy -- schedule it in. The next season will probably be in fall again so, can I fit a baby in before then? Probably can, so we'll see if it's doable, yeah."

"I think he'll be able to help a lot and it will not be as stressful as having two kids under 3," Peta revealed. "We've already spoken to him about it a little bit, and he goes between wanting a sister and a brother."
