I get the impression that she does exactly what she wants to do, for whatever her particular reasons are, and that's it. She already had that crazy, non-stop type of modeling career and maybe she wants the option of modeling on the international scene again but doing so very part time. A huge comeback may be something the fans want but Gemma seems to want something else... I really doubt that she just isn't getting more than a few random jobs. The rest of her life seems way higher on her priority list, like she doesn't define herself as a model anymore.
