According to this update (it is a 2 picture sets), it seems that, either, Heidy Pino or Julieta Davidovich is 'leaving' GeorgeModels.
It is confusing, because, Julieta Davidovich has 6 videos on GM, and in the image is a 'welcome' to her. Also, the update is in Julieta's store, but not in Heidy's.
EDIT: Thanks for Heidy's Instagram!
