*New photos of Mariah Carey in concert have reignited pregnancy rumors, and for the umpteenth time,  her husband Nick Cannon is refusing to discuss whether or not his wife is with child – this time, directly to gossip-blogger Perez Hilton.

“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, when confronted with the question by Hilton, who claimed the singer appeared to be carrying pregnancy weight at her concert in Sao Paulo.

Mariah Carey performs during the 2010 Barretos International Rodeo on August 22, 2010 in Barretos, Brazil.

“There comes a point when there’s no denying anything if it were to happen,” Perez countered back at Nick.

“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 answered.

“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,” Cannon continued.

“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,” Nick added.
