Nick Cannon Has Baby Names for Mariah CareyDespite rumors Mariah Carey, 40, is pregnant with her first child -- or possibly twins, depending on who's spitting the gossip -- husband Nick Cannon, 29, is keeping the speculation in check.

"If & when my wife is ready to make ANY announcements about private matters she will do it personally. Thanks for being respectful," Cannon tweeted yesterday.

But nothing's stopping him from joking about baby names. "We're gonna do it like George Foreman," he said this morning on his radio show, 'Rollin.' "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."
