I get it. You're expecting a baby (or two or more). But, this whole, let's take a nude photo to remember the time has GOT TO STOP.
But Mariah's face even seems to be saying, "I know I'm being paid to do this, but what the hell was I thinking?" And her husband, Nick Cannon, is totally creepy - squeezing her boobs while covering her nipples and appearing to whisper in her ear. He could be saying, "It's all good!" or anything else to keep Mariah from reaching for a top.
It doesn't get any better here.
I remember when Demi Moore did this.
I'd rather see them not posed. Like this.
Totally more appropriate - especially for the non-famous pregnant ladies. Also not creepy:
