Not long ago, Mariah Carey tweeted a picture of her huge pregnant belly, decorated with a butterfly.  Now she's gone all Demi Moore on us, posting naked for the cover of Life & Style magazine, showing off her enormous baby bump.  Her twins with hubby Nick cannon are due next month, but may arrive earlier.

Mariah tells the magazine,

I was feeling very vulnerable about taking pictures at all right now, but then, I didn't want to miss this opportunity to document this once-in-a-lifetime experience.  My ultimate goal was to share this incredibly personal moment with my true fans."

During the photo shoot, Mariah says that the twins -- a boy and a girl -- were

kicking almost the entire time," adding, "Especially the girl -- clearly, she's a diva in training."

What do you think about these kind of images being put on the cover of magazines?
