Mariah Carey and Nick CannonMariah Carey's recent performance in Brazil reignited speculation that the singer is pregnant. The 'Obsessed' singer had noticeably exchanged her signature hip-hugging dresses for oversized clothing that hid her bodacious curves. Although her husband Nick Cannon is playing coy about her growing belly, the couple aren't exactly denying the pregnancy rumors.

Mariah's publicist, Cindi Berger, told PopEater's Naughty But Nice Rob Shuter that Carey has seen all the coverage about her rumored pregnancy and "appreciates everyone's well wishes."

"But she's superstitious," Berger continues, tellingly. "When the time is right for her to say something, I'm sure she will."

While the couple, who wed in 2008, has yet to confirm the news, sources close to the singer tell PopEater the 40-year-old diva is indeed pregnant.
