I love Isabeli but it’s no secret that she doesn’t work as much because she has a tendency to run her mouth and the powers that be don’t appreciate it. She said a couple years ago that she no longer walks for Versace because the stylist (Jacob K) hates her. It didn’t win her any favors.
To be honest, she doesn’t seem to be saying anything particularly bad about Adriana. She just says that she kept more to herself and wasn’t part of the Brazilian gang, which if you know her personality is probably true. Now the jealousy of Gisele seems to be a bit of an overreach.
In retrospect she may be jealous that they had angel contracts and she didn’t but that was her personal choice to pass on the contract. VS went to Isabeli, she declined, then to Ana BB and then she declined, and finally to Alessandra.
