Mariah Carey's husband Nick Cannon says someone in their family is expecting -- but he wouldn't say that it's his divalicious wife.

Asked if Carey, 41, is pregnant, Cannon, 29, said on E!'s Daily 10 Thursday: "That's news to me." He then joked, "I do want to make a big announcement ... Russell terrier puppy Zha Zha is pregnant again!"

Carey fueled baby rumors earlier this week by dropping out of Tyler Perry's new film, set to begin shooting next month.

"She is not doing the movie because her doctor advised her not to," her rep tells "More than that I cannot comment further."

Earlier this month, Cannon -- who recently renewed his vows with Carey -- hinted to Us that a little one might be on the way.

"Her schedule is starting to calm down, you never know..." he coyly told Us. "In the next year or two, the rumors might come true."
