Doing a Demi! Kim Kardashian hits back at the body-shamers with her most revealing selfie

They say a picture paints a thousand words, but when it comes to Kim Kardashian's self-styled selfies, we're thinking it's more around the million mark.

The reality TV star posted this totally nude snap to Instagram, hitting out critics who claim her baby bump isn't real.

And it's done the job as we were even dubious she was rocking a faux bump until now. Well, it did appear to vanish on certain days.

With the picture, the 34-year-old wrote: "Everyone's body is different, every pregnancy is very different."

Mum-of-one Kim announced her pregnancy in May and is expecting in December. We've said it before and we'll say it again, baby Jeezus born on Christmas Day. It has to happen, right?
