Singer Mariah Carey and husband Nick Cannon are expecting their first child: after a recent performance in Brazil, Radar Online is now able to confirm that, indeed, the diva is four months pregnant.

Though this is not the first time rumors of this type get out in the media, there can hardly be any doubt about it this time: after trying repeatedly to get pregnant, the singer is finally with child.

The reason Mariah and Nick are not confirming this for the media is that they would rather they kept the happy news to themselves, perhaps out of fear that something might go wrong.

Though Mariah shares a very close relationship with her fans, she has solid reason for choosing not to disclose this information to them just yet – but she will probably do so in a few months.

“Nick has been telling friends how excited he is to be a dad. Mariah has tried so hard to get pregnant. She definitely wanted to get pregnant,” a source close to the singer says for Radar.

“She’s very excited. She wants to wait as close to full term as possible before going public with the news to her fans,” the same spy explains.

Asked about the ongoing rumors, which are almost impossible to deny if confronted with recent pics and video footage, Nick Cannon did his best to avoid a straight answer, as Billboard can confirm.

Without saying yes or no to questions about the pregnancy, he only insisted Mariah would let her fans know of anything important going on in her life when the time was right for her to do so.

Until then, he couldn’t possibly say anything else, he added.

“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,” Cannon said.

“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, when it came to talk about Mariah’s definitely heavier figure.

Below is the video of Mariah Carey performing in Brazil over the weekend – word in the blogosphere has it there’s definitely a baby bump there. You be the judge of that.
