I don't believe this. It's just her perspect of view. IMO Erin is acting all weird all because she's no longer an angel. She should move on and stop holding a grudge. Sure it's sad VS stopped with her because she was getting too 'fat' but please don't talk shitty about your fellow ex-coworkers.
You see Rosie and Candice are very close but also rarely see eachother. Just like Behati and Candice btw. Model life's are very busy with traveling and all, so i can imagine if you don't work for the same company anymore you see eachother less and less. And then contact just fades away, definitly if you aren't that close and only hanged out during the time you worked together. I think that's the case with Erin and the angels. I find it very hard to believe they distance themself just because she was sick.
Never liked Erin and never will.
