She used to smoke–and I assume she’s no longer smoking since she’s pregnant–but then she also didn’t give a shit about visiting countries with Zika warnings, so hey, maybe she still does smoke. Nobody really knows for sure…
But, yeah, I’ve heard the comments that she is very thin before. She looks more fleshed out now that she’s pregnant than she did before, but when you consider that the camera “adds 10 pounds,” then she probably still does look pretty skinny.
