Not by judging of the few pictures I've seen of her during pregnancy, atleast. She strikes me as the type that doesn't "let her self go" under any type of circumstances, and didn't she say that she only gained a little weight under the pregnancy? I doubt that just happened.
I'm not trying to bash her by any means, there's nothing wrong with taking care of yourself while you are "growing" a baby aswell

But she seems very perfectionist when it comes to her own appearance, and sometimes she looks so botoxed/alien it's downright scary.. I don't think she knows how gorgeous she is, and in my opinion always has been.
