"We're gonna do it like George Foreman," Cannon, 29, joked on his morning radio show. "We're gonna name all of our kids Mariah no matter if they're boys or girls. ... Mariah No. 1, Boy Mariah, Man Mariah, Tall Mariah. It's gonna be a house full of people named Mariah."
Foreman, 61, the former world-champion boxer, famously named all his five sons George.
In terms of the ongoing speculation that the pop superstar, 40, is pregnant, Cannon echoed what he wrote on Twitter Wednesday, which is that his wife will speak publicly, if she has any news, when the time is right for her.
"I'm pretty sure that when my wife is ready to make any announcement it won't be to the media, to the public, first," he said. "She'll tell her family, she'll tell her friends, and then, you know, when she's ready to share with the rest of the world, who is her extended family and friends, then she'll let everybody know."
She knows what she's doing, Cannon added. "My wife has been in this business for a long time and dealt with so many things, she knows how to handle herself. She's a very, very strong woman, probably the strongest woman I know, and I love her dearly. So, when she tells me something, I'll tell y'all, probably after I tell my mama."
Cannon also said he and Carey do want to have kids, but it isn't something you can always schedule precisely.
"It's probably a question I get asked more than anything: When are we having children?" he said. "Of course, being married you want to start a family. ... But you can't say, 'Well yeah, next week, Thursday, on the 4th, we gonna do this, and then we plan on having the child.' You know, you gotta leave all that stuff to God. That's in God's hands. So, when it happens, it happens, and we'll be happy."
