Jim Carrey to be a Grandfather!

By JustMommies staff

Jim Carrey's daughter Jane Carrey, 22, announced that she is pregnant with a baby boy.

The singer tells ET Canada that she and her fiance, Alex Santana, are expecting their first son next spring. Jane says they have already decided on a name -- Jackson Riley. The couple is set to wed later this month. She says her famous dad will definitely walk her down the aisle as well!

People reports that Jane has been having very specific pregnancy cravings lately -- and it's all about donuts! "I’ll smell donuts when donuts are nowhere near and I’ll be like, ‘Who’s got donuts?’ There’s no donuts in the building."
