Nicole Ritchie and a baby?

So it has been confirmed Nicole Ritchie is pregnant by her rocker boyfriend Joel. Whilst many people are speculating when she became pregnant, are they gonna get hitched? To be honest I just want to know with the most ridiculous skinny frame I have ever seen, how did she do it, between the lack of skin and rib cage, where is the room for a baby? At least maybe she'll eat now, well for one anyway!
