They aren't even born yet ... but they're already making headlines.

Yes, we're talking about the celebrity babies due in 2013.

Of course, no baby will be more anticipated than the child of Prince William and Kate Middleton. The Duchess will be giving birth to the future King or Queen of England.

While there are reports that Jessica Simpson and Jennifer Aniston are both expecting, even their babies won't trump the royal one.
