The 43-year-old who has joined the series for the second season said she was shocked by how she was received by other housewives Gina Liano, Jackie Gilles, Chyka Keebaugh, Lydia Schiavello, Janet Roach and fellow new cast member Pettifleur Berenger, reports The Daily Mail.
'They treated me like I was from another planet… It was bad, worse than I expected,' she said of the group dynamics on the Arena show.
The blonde, contemporary art collector previously based in Sydney hopes viewers can learn something from her experiences on the show.
'I’m not the best role model, but I certainly show people how to handle a bully,' she said in the interview.
Gamble also revealed some behind-the-scenes gossip on the production of the reality show, explaining the stars are wired up to their microphones before given the opportunity to 'run wild' and 'get really tanked'.
