What's bigger: belly or butt?

That's the question jewelry designer Lorraine Schwartz posed as she posted the Instagram pic of friend Kim Kardashian we're showing below.

On one hand, the 32-year-old's belly seems to be expanding exponentially. Seriously, how close to her due date is she? Because she looks like a balloon on the verge of popping.

On the other, the reality star has always been known for the junk she's sporting in the trunk, if you know what we mean. So much so that we have to wonder if Jennifer Lopez might sue for infringement.

What do you think? Which is bigger? Sound off with the blue buttons below.
