Mariah Carey Baby Bump Photos, Nick Cannon Adresses Pregnancy Rumors

New photos of Mariah Carey performing in Brazil have sparked more speculation that the singer, 41, is pregnant, but her husband Nick Cannon is keeping mum about it.

"I've said it before and I'll say it time and time again -- when my wife feels like talking about whatever she wants to talk about, you will hear it directly from her," he said on his radio show on New York's 92.3 FM Monday.

"Honestly ... I say this to you so you can tell whoever it is you've got to tell, we all know it's extremely personal, and it is for a woman to deal with things with her body, and especially when dealing with the idea of childbirth and all that stuff," he added.

"We know that we're public figures and that's something but ... that's something that you want to keep near and dear ... until you're 100 percent sure in any situation ... There's a certain time limit that you're supposed to wait before you actually can officially say that you are. You've got to take all those things into factor and it gets really heightened when you're one of the most famous people in the world because you don't want to mislead anybody," Cannon, 29, said.
