The singer's withdrawal from new film For Colored Girls Who Have Considered Suicide When the Rainbow Is Enuf earlier this week sparked speculation that she is pregnant.
US Weekly quotes Cannon as saying: "Her schedule is starting to calm down, you never know. In the next year or two, the rumours might come true."
Carey's rep added: "She is not doing the movie because her doctor advised her not to. More than that I cannot comment further."
However, Cannon did announce that their dog Zha Zha is pregnant with a litter of puppies.
"I do want to make a big announcement... Russell terrier puppy Zha Zha is pregnant again!" he said.
