She looks pretty pregnant to me but wouldn’t that be the biggest shock if she was having a hysterical pregnancy.
That’s just an illusion created by the dress. I’m 7 months along and the appearance of my bump changes drastically depending on what I’m wearing and what position I’m in. Heck, I was sitting next to an acquaintance on a couch this past weekend at a party and she didn’t notice I was pregnant until I stood up. It freaked her out.
