The breast size looks right to me, based on various photos I've seen recently (mostly Score and/or Voluptuous). Apart from the fact that she did claim to have gained a few pounds, due to the perspective distortion at the lower part of the photo I think that this shot was taken with a short focal length (wide angle) lens. Such lenses, at a close up, tend to exaggerate the scale of things placed closer in the field of view, relative to those things slightly further back.
Then again, I don't know her (or any model) personally, so who knows what might be up in her personal life. I wish her well, regardless. And if she continues to gain weight, I think that she'll just continue to look better and better.
