mariah230.jpgMariah Carey is keeping the world guessing as to whether or not she's carrying Nick Cannon's bun in her oven! However, the songbird, 41, spoke out via her website about the speculation that she's pregnant.

Carey writes:

    “I appreciate everyone’s well wishes. But I am very superstitious. When the time is right, everyone will know–even Cindi Berger [her publicist]."


Just last week, Miss Carey was photographed wearing a maternity dress in Sao Paulo, Brazil which reignited the rumors.

Hubby Nick Cannon, 29, has remained tight-lipped ... however he did say this on his NYC radio show:

    "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."


Oh, Mariah ... it's just a matter of time before we'll be calling you Mama Mimi!
