But if you haven't been a pregnant Kim Kardashian yourself, you might not realize that what you're saying can be perceived as inappropriate. Here are 6 phrases that are off limits.

1. "Did you use a surrogate and are you wearing a prosthetic belly?"

Do not ask a pregnant Kim Kardashian if she is secretly using a surrogate to carry her baby and is actually wearing a prosthetic belly to fool the public. You might not realize it, but this type of question can seem very presumptuous.
