Mariah Carey in Sao Paolo sporting a dress from maternity store A Pea in the Pod

*The baby rumors surrounding Mariah Carey are picking up more steam than usual with new reports that she is four months pregnant and was spotted in a maternity dress.

Although Cannon dodged the question yesterday (Aug. 24) on his radio show, Radar Online says it has a source who “confirmed” that Mariah, 40, and Nick Cannon, 29, are expecting their first child.

Fueling the fire is the above paparazzi pic of Carey from last week wearing a  Spaghetti Strap Halter Maternity Maxi Dress ($140) from maternity store A Pea In the Pod.

According to Radar Online, Nick has been sharing the news with close friends only.

“Mariah has tried so hard to get pregnant,” a source told the website, adding that the singer has no plans to announce her pregnancy in the near future. “She’s very excited. She wants to wait as close to full term as possible before going public with the news to her fans.”
