Is she, or isn't she?

Mariah Carey — rumored to be expecting her first child with husband Nick Cannon — won't say yet.

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

Pregnancy rumors swirled earlier this summer and reignited last week when the singer, 41, stepped out in Sao Paulo, Brazil, in a $140 Pea in the Pod Spaghetti Strap Halter Maternity Maxi Dress.

Cannon, 29, also refuses to talk.

On his NYC radio show Monday, he said: "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."
