"If & when my wife is ready to make ANY announcements about private matters she will do it personally," Cannon tweeted. "Thanks for being respectful GodBless."
"My heart goes out to any woman who has to deal with public scrutiny and speculation pertaining to their private life REAL TALK!" Cannon added.
Carey, who has dodged pregnancy rumors since she and Cannon married in 2008, fueled another round of speculation this month when she pulled out of her role in Tyler Perry's next film, "Colored Girls Who Have Considered Suicide When the Rainbow Is Enuf." On Wednesday, Radar Online quoted an unnamed source who confirmed that Carey is pregnant. "They're both very excited and very happy," said the source. "Mariah and Nick want to keep the pregnancy quiet as long as they can."
Carey's publicist, Cindi Berger, told Radar, "I'm not at liberty to discuss Mariah's personal life at this time."
Though Cannon declined to speak directly on Carey's pregnancy, he recently addressed another recent tabloid rumor about him and his wife to Billboard.com - the report that they'd be joining Simon Cowell next year as judges on the U.S. version of "The X Factor."
"I keep hearing that rumor!" Cannon told Billboard.com. "Simon Cowell is definitely a close friend of our family, but we haven't received any offers in the mail yet."
"If my wife and I worked together it would definitely have to be something really special," he added. "Simon Cowell is the right dude to be in business with -- and I mean, he's my boss on 'America's Got Talent' right now, so I'm probably not going to turn him down."
