Did the rest of the cast really think the A list reality star from multiple network and cable shows was their friend? It isn't as if they hung out when they were not filming when she was on the show, so I'm not sure what they are complaining about now.
The franchise that has multiple cities will play along for a bit with the east coaster, but she needs them far more than they need her. I suppose she thinks she is the big name now that the big name quit. The thing is though, she was going to be pushed out in the next year or two anyway as they try and reboot way younger.
If there was a buck to possibly be made exploiting her relationship or a marriage, you know this A- list reality star from multiple shows would do it. There won't be any secrets when money is available.
This Housewife is about to learn a hard lesson that what you can say about someone on a reality show where everyone signs up to be dragged and shamed is not the same as the real world. Calling out a celebrity for being on drugs when the Housewife had no clue at all, is going to end up as a lawsuit.
