From Instagram, announcing her pregnancy. With black paint.

She is nude, kneeling, and covering her breasts with her arm:

It reminds me of your last find Masher - this:

Yeah, not a bad pic, i like the way she's probably covered on her hair and face, not just a little bit here and there.

It's now made it way in the papers (although as stated originally from instragram).

You forgot to get a waiver from Megan Fox to post the picture.
